"Double I type 2 section – di2" causes error in static pushover analysis
Posted: 10 Jun 2023, 13:06
Dear all,
when modelling a URM building with some "Double I type 2 section – di2" steel profiles, the following error is generated when trying to run a static pushover analysis in SeismoStruct 2023 Release-2 Build-25:
"""
Errors detected while sending data to solver:
Analysis 1
Errors detected in Classes Module:
Definition of elastic frame element classes: The element parameters should be larger or equal to zero. SeismoStruct cannot run the analysis.
"""
The underlying material type is a Menegotto-Pinto steel model. I was able to narrow down the error to the use of the di2 sections. If I replace them with "Double I type 1 section – di1" with exactly the same dimensions and zero "Flange to Flange distance" the above error does not occur.
Best regards,
Paulo
