Problem Description
In a Pdelta analysis with tension/compression, the pdelta effect is not considered in section force calculations unless each load case is followed by the PDELTA ANALYSIS and CHANGE.
Steps to Reproduce
- Have two exact same models with PDELTA ANALYSIS and tension/compression.
- In one use PDELTA ANALYSIS and CHANGE after every load case.
- In the other use the PDELTA ANALYSIS command once at the end.
- Analzye both models and observe that the results do not match.
Workaround
Provide PDELTA ANALYSIS and CHANGE command after each load case for which analysis/design is to be carried out
Solution
This has been addressed in 20.07.11.70
