I have a 3D structure. For IDA analyze, with three time history curves (for each direction), in IDA tab of the seismostruct, there is only one option for only one direction. Why? Could you please help me how can I analyze a structure with three time history curves and my considered coefficients for such curves?
I think it should be possible to an IDA analyze a 3D structure with three time history curves by seismostruct, not for only one direction. It is for 2D structures!

Re: IDA for 3-direction
With SeismoStruct, you can run IDA with acceleration time-histories in all 3 directions, there is no problem with that.
The directions indicated in the IDA tab are just for the derivation of the IDA envelope.

Re: IDA for 3-direction
Hey,
Does anyone know how can we get IDA curve with spectral acceleration vs maximum drift as the parameters. It would be helpful for me to carry out my research.

In the post-Processor, in the IDA Envelope tab you will be able to get the Maximum Drift vs. Base Shear plot for all the analyses. I do not know if this can be useful.
