The output you are getting is not bending moment but it is the pseudotime. There must be something wrong with your code due to which it is unable to record the stress and strain and you are only getting pseudotime as an output. Thank you for your reply. Could you please help me to see how to modify...

Why do you have the 2 in '-ele 1 2 section...'? I think I know what you mean，Are you saying this should be the case， recorder Element -file Element1.out -time -ele 1 Section 1 fiber 5.6 4.8 strainstress I tried again, Element1.out still got the bending moment Rather than strainstress Can you help m...

thankyou for you reply thanyou xiexie

I add pattern MultiSupport 1 and 3 to 260 point , add pattern MultiSupport 2 and 4 to 261 point, But ultimately only pattern MultiSupport 3 and 4 have impacts on the results Where is the problem？ Looking forward to your reply This is part of my code： puts "Transient analysis" set xDamp 0.0...

Yes, Plain and Multisupport patterns can be used together. Multisupport can use any imposed displacement, velocity, or acceleration. This is part of my code： set xDamp 0.05; set nEigenI 1; set nEigenJ 2; set lambdaN [eigen [expr $nEigenJ]]; set lambdaI [lindex $lambdaN [expr $nEigenI-1]]; set lambd...

I would like to ask the first question: can pattern Plain and Pattern Multisupport not be used together? The second question is whether pattern Multisupport can only add ground vibration. I am looking forward to your reply
