switching between solver in P-Delta analysis

[parhyang]

hi, i encounter a problem in P-Delta analysis with OpenSees solver. Previous version is working properly when i switch between OOFEM and OpenSees solver, both results are identical. Attached sample input files, is there something changed and i miss? thank you.

Hello,
Pdelta transformation in OpenSees is supported only for elasticBeamColumn and not for ElasticTimoshenkoBeam. Simply add “noShearK” equal to 1 in element properties.
ps.
there’s no change in behaviour of previous versions.

thank you for clarification and hints, probably my previous successful running are disabled in shear deformation of beams in solver preferences.

Yes, this could be the reason – the option “Shear deformation of beams” is equivalent to assing noShearK=1 to all beams.
