The goal is to reduce costs by reducing time and improving quality. 2 Application: This Work Book can be used for single tank within a single containment area or can be used for multiple tanks within a single containment area. 3 4 5 Contents: There are five (5) sheets included. Sheet "1 (this sheet) is the instructions and Notes. Sheet #2 is a list of some of the most common API Storage Tank sizes . Space is included so the user can record other sizes consistent with project specific requirements . Sheet #3 is the work sheet for the Single Tank application. Sheet #4 is the work Sheet for the multiple tank application . Sheet #5 is a two page work sheet: Page 1 is for the Dike Detail and page 2 is for the Tank Pad Detail. Tank Data: A) Collect a list of Tanks for the Project . This list must include the sizes (in Barrels), the Tank Types and the Commodities. B) Determine if there is a Local or Client imposed Code that defines Grouping or separation of Tank types or Commodities. If there are Tanks on the project list that are not included on Sheet #2 then add them in the "Yellow" spaces provided and in this case only hit "Save". Civil/Structural Data: Meet with the appropriate Civil/Structural Group and have them define preliminary guidelines for A) the Angle of Repose of the material to be used for the Dikes (Berms, Bungs, etc.), the recommended maximum height of the Dikes and for B) The proposed approach to Tank Pad profiles (Height and configuration). 6 The Task: Add the Dike Height and Angle of Repose data into Page 1 of Sheet #5. Add the Tank Pad height Data to Page 2 of Sheet #5 7 For Single Tank Installation: Use Sheet #3. Enter all the data required (and Optional) Data in the "Yellow" user entry boxes. The Form and the built-in formulas will do the work for you. 8 9 For Multiple Tank Installation: Use Sheet #4. Enter all the data required (and Optional) Data in the "Yellow" user entry boxes. The Form and the built-in formulas will do most of the work for you. With this grouping you must select and enter a choice for the "Width" of the Containment Area. This is a "Trial and Error" method until you get the shape that fits the project needs . Quitting and Closing: It is recommended that before closing the program that Copies of all Sheets be printed out for all Tank configurations completed. When closing the program do not save the data. This will allow you to start with a clean Work Book for the next Tank configuration. Note: Each Sheet of this Work Book is Password protected. In order to make a change to a "cell" that is not "Yellow" the Sheet must be "unprotected" using the password. This Password will be furnished on request.

The stress values in this Table may be interpolated to determine values for intermediate temperatures. When used for Section III Class MC design, the stress values listed herein shall be multiplied by a factor of 1.1 (NE-3112.4); these values shall be considered as design stress intensities or allowable stress values as required by NE-3200 or NE-3300, resp For Section VIII applications, stress values in restricted shear such as dowel bolts or similar construction in which the shearing member is so restricted that the section under consideration would fail without reduction of area shall be 0.80 times the va For Section VIII applications, stress values in bearing shall be 1.60 times the values in the above Table. Stress values for -20 to 100oF are applicable for colder temperatures when toughness requirements of Section III or Section VIII are met. Due to the relatively low yield strength of these materials, these higher stress values were established at temperatures where the short time tensile properties govern to permit the use of these alloys where slightly greater deformation is acceptable. The G42 For Section I, use is limited to PEB-5.3.
