but when i set the Peak ground motion as 0.05g, and I can get the result, and the analysis get through.
so Is there any methods to analyze the model with different parameters in different time?

Could you give me more details ?
I will be very thankful for your help.

Recently ,I construct a 10 story plane frame in opensees. There are three parts: model , adding seismic load , analysis . the model is good ,for there are none warnings comes out. I take the bigbear records as the seismic load ,and modify the peak acceleration as 0.224 g . And then ,I set the analys...

I was greatly surprised by your replies .It enlighten me greatly . But ,there are some difficulties:I hasnt make any effort to read the C++ source codes. and so without any instructions to the source codes of equation object ,I will pour too much time to understand the property of the equation objec...

beg your replies eagerly.

could you help me,any suggestions will be very important for me

need your help eagerly

Recently,I construct a 10 story structure in opensees. and when I load the Mx ,some results is abnormal . Following is my tcl commands: model basic -ndm 3 -ndf 6 set conBC 1 set stlBC 2 set millin 1000000 set revmilli 0.000001 ##（N/m2) uniaxialMaterial Concrete02 $conBC [expr -20.1*$millin] -0.002...

got is !!!
sorry for interuptions

I got it ,thanks .

the notion is a problem for me .
I seek for the answeer thousands of times .
Is there any one give me some directions ?

could you give me your experience in this field?
And what do you think about this problem?

Your advice is very important.
Under your instruction,I make the analysis successfully.
Thank you very very a lot.

hi, I construct a three model 10 story structure . I want to get the whole sturcture stiff matrix at the first step of seism analysis, and the stiff matrix at the last step . Through comapring the two stiff matrixs,I can get the Information of the damage state of the whole structure suffering a larg...

Hi, I want to record the moment and the curvature at the ends of an element at every time step during seism ananlysis , and my element type is Nonlinear Beam Column element . And my model is 3D model. 3D MODEL SEEMS DIFFICULT. Now ,I almost in despair. How should I do? Is there any necessary to set ...
