Answer: Attention: Be sure to review, AutoPIPE help section: Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches> Support> Rod support. When modeling any type of support in AutoPIPE it best to understand the functionality of all the support types in AutoPIPE. Therefore please see the following AutoPIPE help section: Help > Contents> Contents Tab> Command Reference> Component Reference >Support > Supports Overview. Here you will see a grid of each support with relative support options, and support's Bering direction (vital information). Now that you understand this data, let us put it to work creating a Vertical Rod support. Now, describe the support your trying to model: 1. what is the functionality of a vertical rod support? answer: mainly to support a pipe in the vertical direction 2. what kind of gaps does a vertical rod support have? answer: No gap down, may or may not have a small gap above the pipe, able to move laterally, able to move axially. With this information add as many AutoPIPE support at the same node point to achieve this support requirement. From the online help chart mentioned above find Step #1, insert a support at the pipe node point by using the toolbar button or Insert> Support menu command. On the support dialog screen, change Support Type = V-Stop, enable the Rod Hanger check-box, modify any additional settings as needed (see online help for details on each setting), and press OK button to insert the support. Do we need to add any other support at this location or does this single support meet our requirements above? Answer: No other support are required as a V-stop: a. Assumed rigid in the downward direction with gap = 0. b. Assumed rigid in the up direction after the gap above, 0.25 inches closes. c. Able to move lateral as the bearing direction is Vertical only. d. Able to move axial as the bearing direction is Vertical only. Complete support will look like this: Note: see the following link to model Pendulum swinging motion: Model pendulum swing of a pipe on a rod support in AutoPIPE See Also Bentley AutoPIPE External Links Bentley Technical Support KnowledgeBase Bentley LEARN Server Comments or Corrections?
