Re: Problems of convergence. Soft stoy or not?

Thanks for the help. I did the test to increase the columns of the first level W14X90 the% RS to 60 and the chord rotation in the criterion of failure I changed it from the value I had from 4θy (chord rotation yield) to 6θy and it was completed with a target displacement the 0.35 m But my question i...

Problems of convergence. Soft stoy or not?

I'm modeling a 4-level steel frame building in Seismostruct for a pushover analysis. I am having problems of convergence and I have followed the recommendations that the program gives me, the message that appears to me when stopping the analysis is this: "The structural model can not withstand the d...

Nodal displacement rare behauvior

Hello everyone. I would like your help: I have modeled a building of 4-level steel frames (without bracings). The slab is concrete and I have modeled it as a rigid diaphragm. When analyzing the building with eigenvalues the predominant period (mode 1) gives me equal to 0.88 s (normal value) BUT the ...

Re: Seismostruct found differences between the input.spf and

I have to add that it is a 4-story building. Half of story 4 is a roof with sloping roof and the other half is concrete slab. What I did was determine the loads of the sloping roof that support the columns of the fourth level through the software ETABS. All the other dead and live loads I applied to...

System requirements recommended

Hi. I want to buy a machine to use seismostruct to perform IDA analysis in buildings of up to 4 levels. What would be advisable in terms of processor, video card, RAM and other important features taking into account the time taken by these analyzes? Would it be better to buy a desktop computer or a ...
