thanks for your reply
but my problem is calculating modal excitation factor for rotational degrees of freedom when lumped mass is used in the model.

Dear colleague

Would you please inform me what is your reference for calculating modal excitation factor for rotational degrees of freedom? and if you have simple example I appreciate if you share it.

Best Regards

Dear Colleague
Would you please guide me how Seismostruct transform forces in gauss point to global forces in the ends of element in fiber elements approach?

Dear Seismosoft

Would you please guide me how SeismoSignal calculate inelastic spectra with only ductility factor and post-hardening ratio?(how it recognize point of yielding of SDOF system during nonlinear time history analysis?)

Best regards

Dear seismosoft

can you please guide me how can I increase accuracy between target and match spectrum in the setting module of SeismoMatch software?

Dear colleagues

How can model elasto-perfect plastic link element with initial gap in both tension and compression with seismostruct?

Dear Seismosoft
If I have academic license key for your different product and want to download new version of them,I should get new license key or can use previous license for new version of product?

Dear Seismosoft

I want to know can I extract nonlinear stiffness matrix at each step in pushover analysis of structure?

Thanks in advanced
