Only the displacement serie was input in the multi-support excitation case, and it was obtained by using the SeismoSignal with a ac...

Hello all, I built a FEM of a cable-stayed bridge in OpenSees for seismic analysis. Model A is loaded by unform exciatiaion and Model B is loaded by multiplesupport exciation. The displacement time-history used in Model B was obtained by two times integration of an earthquake acceleration time-histo...

Hello,

I have meet the same problem with you. So have you figure out this problem?
