These differences are related to small differences in the initial stiffness between the two types of elements, DBPH and FBPH. Whereas in FBPH the stiffness is ...

Hello Seismosoft team.

I ran into a problem regarding the elastic dynamic analysis. I used DBPH and FBPH and realized that the values of the eigenperiods and so the response of the structure is slightly different. I know these type of elements are only used for inelastic analyses, but i saw these ...

Hello .

I read this topic and i have a question regarding the type of elements used. If DBPH is used then the pushover starts with cracked stiffness of the elements (My*Ls/3θy which is a mean value) and if FBPH or FB elements are used then the stiffness is the uncracked one and changes (lowers its ...

I think it is possible if you just expand your txt (which has time and acceleration) with values of the other earthquake record but be careful to change the time at the txt of the 2nd event.

Dear Seismostruct team.

When i do pushover analysis i want the strength of the members to fall to 25 % (and remain) when they fail as KAN.EPE suggests. So i go to pushover analysis-check via code and there i can do that. The program has the option to do that for both shear and moment. I want to ...
