and some appliments

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.

for element: 35(dW: << 1712.25) , Where is the problem

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...
