Hi I want to get all fibers' stress-strain response of a section. Which Recorder command can I use ? So far, I find a command: recorder Element -file ele1sec1Force.out –time -ele 1 section 1 fiber $y $z <$matID> stressStrain But only one fiber can be monitored with this command, it's so hard to moni...

Thank you for your reply! I have a new problem now, please help me. I draw the section stiffness curve varying with seismic time-history by MATLAB. But the curve is not monotonous , it descends and recovers sharply at some time point. I think there is no wrong with my model. So, I want to know what ...

hello I want to use the Stiffness Recorder to capture the stiffness of a section and I got the output file in which four values (except time history) are shown in a row. but, I don't know what the four values represent for. In other words, are they the four elements of the stiffness matrices ? pleas...

Dear professor I aimed to build a model to execute a pushover analysis of a cantilever in 2D. I used the ZeroLengthSection element to simulate the effect of reinforcements slipping at the fixed end of the model. Here is my scripts : ############################### wipe file mkdir Data5 model basic -...

I want to set up a single pier model considering the bond slip of longitudinal reinforcement for Pushover analysis.The code is as follows,But I got the following error.Please check it out for me. ################################## wipe file mkdir Data3 model Basic Builder -ndm 2 -ndf 3 source units....
