Can you provide me a reference for where to use flexible anchor and where to use rigid anchor. In addition, Can you guide me for the use of supports as rigid or flexible. Does Bentley provide some literature for modeling of standard pipe supports in AutoPIPE?
Modeling of typical pipe supports can be found in the following online help location:
Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches> Supports.
Some additional elbow supports can be found under:
Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches> Bend> Base supported elbow.
Otherwise, having a clear understanding of the 9 different supports in AutoPIPE, how each support behaves and their limitations, a person could model most of the typical pipe support designs used in industry with one or more of the 9 supports at the same node point.
With regards to using a flexible or rigid support / anchor, use a flexible support / anchor when you know the flexibility and movement at a support node point. If you do not know the flexibility of a support / anchor, you have 2 choices: 1. model with rigid support / anchor or 2. make an engineering judgement and enter a flexibility value. Due to liability law suits, Bentley cannot not provide design decisions in a given scenario, but will be able to help you understand the difference and how the application functions. For a references about flexible / rigid anchors, see the following online help:
