"BS7159" Piping Code Enhancements for AutoPIPE

Note: if an enhancement or defect has not been added to the program, log an Service request for that enhancement. The more requests logged per an enhancement, the quicker the CAE development team will add that feature to the program.

The following enhancements and defects have already been requested:


BS 7159: K factor incorrectly set as 0.6 instead of 1.0 for occasional stress category


K-factor for Occasional category code combinations for BS7159 piping code is incorrectly set as 0.6, resulting in a lower allowable value.

Steps to Reproduce:

1. Create a new BS7159 model

2. Add an anchor and attach a pipe

3. Insert a static earthquake load and add that load to the analysis set

4. Analyze the model

5. Open the Combination dialog and navigate to Code Comb. tab

Notice that the K-factor for the Occasional combination would be incorrectly set as 0.6. BS7159 does not provide a specific K-factor for occasional loads, and this factor should be reset to 1.0.


Manually set the K-factor value for the impacted code combinations using Code comb. tab of Combinations dialog be fore reviewing analysis results.

Development Project: TBD
