I have modeled my composite beam with steel w-section and concrete slab separately i.e by giving two different section properties.(secTag1 and secTag2).Is there anyway I can do Moment curvature analysis of entire composite beam.As far I understood moment curvature can be done for individual sections...

Okay.So for recording the moment in a section do I have to do the moment-curvature analysis??
or is there anyway I can record the moment at the top of the section?

Thank you for your prompt reply. I have one more question,how can I record the moment in a specific fiber of a section element? like,recorder Element -file Element1.out -time -ele 1 section 1 fiber 0.10 0.10 stressStrain is given to find the stress strain at specific fiber of the section.But that op...

Thankyou for Prompt reply.
But when am using those recorders my output file is empty.Can you please let me know why this is happening?

Hello!!
I am unable to find the force and deformation recorder for zero-length element.
Can you please help me out!!
Thanks in advance

Hey! When am trying to analyze my model its returning a -3 error flag as I increase the Analyze increment i.e,Analyze 10 is working fine but Analyse 100 is returning a convergence failure when am doing plain pattern Linear load application.But when am changing it to plain pattern Constant both analy...
