thank your help!

no , please tell me how to do that.and by the way , the pattern tag need to change everytime ,right? thank you!

hi, I am doing the static pushover, I want to change the load pattern at each step. but I dont know how to change the load pattern , when I use the wipeAnalysis command trying to remove the former load pattern. but It seems not to be what I want.so anybody here could tell me how to wipe the former l...

hi, I am doing the pushover analysis. using the recorder command to record the eigenvector of each massnode, you know , the analysis is separating into several steps. I just want the eigenvectors of the modal at each step and each mode, will be stored in each file.for example,if there are 3 steps,fo...

thanks, would you give me some more help about how to program this process with using tcl script?

dear all, I want use the eigenvector outputed by opensees in matlab to calculate the modal participate factor and some parameters. you know , I am doing the nonlinear analysis. so the stiffness is changing during the process, so is the eigenvector. and then I want to input the parameter got from the...

ok,that is fine. thank you for attention

so would you give me some help?

Hi,
have you done some similar analsis? if so,would you be nice to send the examples to me ?my e-mail is zhmkitten@gmail.com
