Start New SSD Project To start a new project please open the SSD and go to menu “File” > “New Project”. Now the “System Information” dialogue opens. Please define project title, project name and project directory first. Note: We recommend to use a local directory for your project files to speed up communication between program and data base. Later on you can zip and save your project data on a company server. http://www.sofistik.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow.html 2/41 10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Now select the code. First select the country flag and then the code. In case you like to use the pure Eurocode without any national annex use the European flag. For further Information about available design checks please read the manuals AQB and BEMESS chapter NORM. http://www.sofistik.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow.html 3/41 10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Warning: If you leave the “System Information” dialogue with “OK” the selected country code is fixed and saved inside the data base. You may NOT change the code later on. With the orientation of the dead load you define the global coordinate system. We are using a red arrow for the xdirection, a green arrow for the ydirection and a blue arrow for the z direction. These colours will be used in all our program modules. Working with SOFiPLUS you have two major options: working with structural elements (automatic mesh generation) working with finite elements (manual meshing) Warning: You must select one option to generate your system. A mix of both methods is not allowed in the graphical input, but can be done with script language inside TEDDY. Warning: If you leave the “System Information” dialogue with “OK” the global coordinate direction is fixed and saved inside the data base. You may NOT change the direction later on. Note: For bridge design we recommend to use a 3d system. http://www.sofistik.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow.html 4/41 de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow.

Specific bridge cross sections will be generated later via SOFiPLUS Cross Section Editor. With a right mouse click on this task you open the context menu. Prestressing System Please add a new SSDtask “Prestressing Systems” to your project. Select the option “New” and generate a new prestressing system.html 9/41 .sofistik.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Hint: Simply use the right mouse click function to generate as many standard cross sections as necessary. http://www.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. You may select one of several system out of the available library. In that case create a new prestressing system and select “User defined”. couplings are organised in groups.g.: bridge geometry information including axes information cross section geometry construction sequence including influence on cross sections and bridge structure concept for element group numbering.html 10/41 . Note: It may be useful to collect and write down all necessary project data before starting with the system generation. springs. System Generation within SOFiPLUS Open SOFiPLUS from the SSD task “SOFiPLUS(X) GUI Model creation”.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Alternatively it is possible to use self defined prestressing systems. quads. You also find the command to define new geometric axes. cross sections and prestressing systems. Inside the SOFiPLUS window all necessary commands are organised in a Sidebar on the left side. http://www.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow.sofistik. All elements such as beams. Tab “System” repeats the options from SSD to define materials. E. Most important is to understand the concept of stations along the axis. For further description please see the SOFiPLUS manual.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Define Bridge Axis First we define a new bridge axis. Just imagine you start walking along the axis for 15.0 m.0 m = 10.0 m and you started at station 10. Go to sidebar > tab “System” and use the right mouse click on the command “Geometric Axes”. Warning: There are only 4 letters and/or numbers allowed for the axis name.0 +15. Now define a new name for your axis.html 11/41 . Now you stop at station 25.0 m . where you define the horizontal alignment of the new bridge axis.. From the possible commands we use the option “New Axis. Confirm the name with “OK” and you will get into the first dialogue.sofistik. http://www.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow.”. This is necessary to add bridge elements later on. http://www. After the horizontal alignment you define the vertical alignment.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Note: We recommend to define your axis longer than your real bridge length.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow.0 m at the beginning and > 10. Usually an extension of 10. Usually you can use the information from the bridge layout drawing.sofistik.0 m at the end of the bridge is sufficient. because you are not allowed to use negative station values.html 12/41 . These variables can be used for the cross sections generation later on.sofistik. Warning: You are not allowed to use variable for material numbers inside the cross section. It is also not possible to use variables for the area of longitudinal reinforcement along the bridge axis. During the meshing process the program will use cross section and variable information to generate all necessary interpolated cross sections for the final finite element mesh. The idea is to define a master cross section with all necessary variables inside. http://www.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS A very important option is to define variables along the bridge axis.html 13/41 .de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. http://www. Placements represent special points along the bridge axis to define supports.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS A next important step is to define placements along the bridge axis. construction points. beginning and end of a bridge structure.html 14/41 . Support placements will be used together with the cross members editor later on to generate support elements and align them automatically with the placements and the axis. They are also very important for the influence line evaluation later on.sofistik. We will use these placements later on for an easy and fast system generation with structural lines and structural areas.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. Define Cross Sections Besides the standard cross sections. It is only possible to define a constant offset in y and z direction. http://www.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. we will now define more complex bridge cross sections. First go to the “System” tab and use the right mouse click on “Cross Sections” . We want to define a new solid cross section for reinforced concrete. Secondary axes can be used for grid structures to define the positions of multiple beams parallel to the bridge axis.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS The last setting during the axis generation is the option to define secondary axes.html 15/41 .sofistik. or also for shell bridges to define the boundary of the bridge including the position where the shell thickness changes. we already defined inside the SSD. Note: At the moment the secondary axis are always parallel to the main bridge axis. This will be done within the Cross Section Editor inside SOFiPLUS. Select the command “Between all placements”. Use the right mouse click to open the context menu and select the command “SEGment on geometric axis”.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Define Bridge Geometry Whether you will use beam or shell elements. Now click on the axis in your drawing area.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow.html 16/41 . The program will automatically generate structural elements between all predefined placements. Go to the tab “Structural Elements” and select a command “Line” or “Area”. The next context menu opens.sofistik. defining the bridge geometry follows the same principles based on an existing bridge axis. http://www. we recommend to use. There are two general options to define tendons inside SOFiPLUS. Define Tendons The tendon geometry and the tendons will be defined graphically inside SOFiPLUS.sofistik.html 17/41 . Please be careful according to the elements you are using inside your system. Simply go to the sidebar tab “Prestressing” and select the command “PT Editor (Developed Geometry)”. Note: In case you do have multiple beams you should use secondary axes to define the beam elements and also to define the tendon geometry.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS For more detailed information please see the different bridge tutorials. For new bridges the “PT Editor” is the most useful command. with “PT Editor” based on bridge axis with “Tendon (Draw)” command based on existing AutoCAD spline or line objects. In http://www.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. Inside the table of Geometry Points you may edit every setting.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS case of beam elements you must use the command below the title “Beam PT: Create and Modify”. Alternatively you may select multiple points and change the settings of all selected points inside the Properties field. The tendon geometry is a spatial spline defined by several Geometry Points.html 18/41 . The general principle is to define one tendon geometry and use this geometry to define multiple tendons if necessary with different start and end stations for every single tendon. http://www.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow.sofistik. In the next step you must select a geometric axis as a reference. Inside the upcoming dialogue all settings for the tendon geometry and the tendons are defined according to the selected bridge axis. The CSM procedure described later will automatically take care of the two parts of the prestressing forces and moments. The first tendon is already set inside the table. Usually this input is not necessary. Important is to define a load case for the static determinant tendon forces and moments.html 19/41 . http://www.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Clicking on the “Edit Tendons” button you get into the Tendon definition dialogue. In case you define a load case (LC0) the static determinate forces and moments are saved separately inside this load case. With the button “Draw Tendon” you may define new tendons with variable start and end stations.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. Usually we recommend to have the necessary loadcases defined before you start defining the tendons.sofistik. Nevertheless it is also possible to generate a new load case right from this dialogue. 10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS After defining all tendons you see a list of all tendons in the sidebar. The cloned tendons have a fixed offset in y and zdirection related to the connected bridge axis. Note: Editing the cloned tendon geometry is not possible.. http://www. you should use a command “Clone..sofistik. Now the tendon generation process is finished.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. In case you want to define new tendons.html 20/41 .” from the context menu. which are parallel to your already defined tendons. Simply use the right mouse click on one of your tendons. In case you want to edit the tendon properties simply double click on the tendons listed in the sidebar. g asphalt) NONE 515X settlement in in every support axis.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Define Actions and Load Cases Before defining any loads it is necessary to define actions and loadcases. e. All these actions are defined inside SOFiPLUS > Loadcase Manager tab “Actions”.g.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. Simply go to tab “Loads” and click on “Loadcase Manager” We recommend the following list of actions. Basic Loads LC Number Description Action 1 selfweight structure NONE 2 additional dead load (e. 10 F mm 8182 uniform temperature load NONE 8384 temperature difference NONE http://www.html 21/41 .

For that reason we recommend to use “Element Loads” for bridge design. self weight and additional dead load. will be used later on inside the construction stage manager (CSM). As we are defining our bridge system according to a bridge axis we also want our loads to follow the axis in case we change the axis parameters of our bridge.

Processing the construction stages the load cases will be connected automatically to the corresponding action types. Connecting LC 1 and 2 to action “NONE” will secure. Later on during the meshing process the loads will be connected to existing elements.html 22/41 .g. In case no element can be found also no loads will be applied. The “Free Loads” are based on the geometric input. that they will not be used twice in manually defined combination later on. According to the code a combination of temperature loads is necessary. UDL Load L_U Group 1 Define Loads Defining loads you may follow two general principles: Element Loads Free Loads Element loads are directly related to a structural point. sofistik. The export dialogue contains two tabs: “Common” and “Text Output”.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Note: If any load is not fully applied to the elements. The settings inside the tab “Text Output” control the amount of output. http://www.html 23/41 . that the maximum amount of output is based on the settings before any calculation. there will be a warning: Mesh System To start the meshing process click on the export button on top left of the sidebar. Usually the default settings are sufficient and you simply click “OK” to start the automatic mesh generation. Later on it is possible to reduce (or increase again) the existing output in Reportbrowser. The standard rule in SOFiSTiK is. But you cannot increase a nonexisting output without a new calculation.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. sofistik.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS http://www.html 24/41 .de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. 75 LC 92 TYPE T TITL 'T summer negdt TN+wm*dT' .

When opening this task all available load cases within the database are selected for analysis.sofistik.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Task “Linear Analysis” For the linear analysis we add the task “Linear Analysis” to our project file.html 26/41 . These pictures are designed for a simple 2d slab project.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. In every SSD task there is a tab “Graphical Output”. but we don’t want to have them used in our project we change the selection manually. Therefore we recommend to switch of all standard graphics. We will generate our own graphics in a separate task “Interactive Graphic”. additional dead load and the single temperature loads in our database. As we do have self weight. In case you have a pile foundation inside your project. Inside the dialogue there are 5 tabs. that the influence line method (module ELLA) cannot produce any bedding results. As a workaround we recommend to use real beam elements and model the bedding with single spring elements.sofistik.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. Select the bridge axis and a section type “EC”.html 27/41 . The program will automatically define all necessary lanes. http://www. Inside the first tab Lanes you define the lanes. Please insert the task “Traffic Loader” into your project and open it. Warning: To run this task it is absolutely necessary to have a full stiffness matrix available inside the data base. where the traffic passes over your bridge. For that reason run the task “Linear Analysis” always before running the task “Traffic Loader”. please note.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Traffic Loads The evaluation of traffic loads is done with the influence line method using the SSD task “Traffic Loader”. 10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Note: The bridge axis used for the traffic loads must be located above all bridge elements.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. Inside the second tab Load Trains you define the load trains.html 28/41 . you must define a new axis above the complete bridge deck to apply all traffic loads correctly. For bridge projects according to the Eurocode you need a loadtrain LM1 300...sofistik. Simply click on the button “Add loadtrain. This task works perfect for paralle lanes. Of course you may define also the fatigue load models http://www. In case of an inclined bridge deck.” and select the necessary loadtrains out of the library of load trains. LM1 200 and LM1 100. In case of non parallel lanes a numerical text based input is necessary. The load case numbers listed here are fixed and will be added to a base loadcase number later on in tab number 4load groups http://www.html 29/41 .10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Inside the third tab Calculation you select all elements you want to have results for. nodes. quads and springs available. There are only results for beams. Simply click on the button “New” to add additional elements. Elements you don’t want will be deleted with a click on button “Delete”.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow.sofistik. A load group contains all loads according to the load group definition inside the Eurocode. Note: An action can be seen as a container with loadcases saved inside this container. Internally the program creates an envelope of all cases.sofistik. all result load cases are saved in the correct actions.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. http://www. Usually we define a load group for the tandem axle loads (TS). Also you define base load case number.html 30/41 . The evaluation cases contain the different load positions in combination with the lanes. Therefore all loadcases of one container have the same properties. for the uniform distributed loads (UDL) and also for the horizontal loads. which has at least 3 digits. To make sure the results will be used correctly in the further project work.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Inside the forth tab Load Groups you define the different load goups and evaluation cases. Later on we simply use all loadcases out of one container by calling the action itself. http://www. or select the elements via ANIMATOR selection.sofistik.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS Inside the fifth tab Plots you define the amount of graphical output. Usually the influence lines are plotted for all elements. We recommend to select only a few elements.html 31/41 . Otherwise you fill in the element number you want.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. This will speed up the analysis and reduces the amount of output. This is important as you may activate and also deactivate single groups of elements at any time during the construction process. This process will effect the forces and moments inside our structure and cannot be neglected. When having prestressed or composite structures the CSM is mandatory. All elements of your structural system are organised in groups.html 32/41 . Construction Stages With the construction stage manager we are able to analyse the whole building process. Before adding the SSD task “Construction Stage Manager (CSM)” from our task library. Construction stages are defined inside cross sections and also inside the tendon geometry and layout already made in SOFiPLUS. you should set up a time line with all necessary incidents.de/documentation/2016/en/tutorials/bridgedesign/workflow/workflow. After the analysis the envelopes can be plotted using a task “Interactive Graphic”. When closing the dialogue the task is processed automatically. because the option “Process immediately” is active per default setting.10/22/2016 General Workflow Bridge Design — SOFiSTiK TUTORiALS After all settings are clear you close the dialogue.
