Y direction base shear problem

Dear all,

I am conducting to project the 3 spanned bridge model in seismostruct. However i have some problem.
First one is about the time history analysis results, logical behav of the system is okay but i couldnt get the correctable result with regard Y direction values.
Second one about the ...

Re: unable to achieve the eigenvalue problem- result is the imaginary or null

I need to clarify one more thing that about bearing hardening ratio parameters.
Default config is assigned by 0,2, however i couldnt decided for my bridge, my elastomer bearing dimensions 250mmx400mmx52mm,
It has 5 plates and plates thickness is 2mm.
Can you suggest any source or research about ...

unable to achieve the eigenvalue problem- result is the imaginary or null

Dear all,

I have issue that couldnt manage on the bridge which has the 3 bays, as you see from subject explanation, i couldnt get the accurate vibrated modes.
Bridge has the piles, standart abutment and piers, plus it has the spring with nonlinear for the shear keys and elastomer designing. The big ...
