Damping energy

[michalbak]

Dear All,

I'm conducting analysis related to damping energy and I have a few questions about your experinces in relation to time-history analysis.

Is there a way to obtain damping energy in the beam element, related to nonlinear material behavior ? At the same time, is it possible to extract from SeismoStruct energy dissipated only due to Rayleigh damping ?

Many thanks in advance for Your help.

Best regards,

Unfortunately, in SeismoStruct there is no output for the measurements of the energy dissipation. The only output that could be of help is the time-history of the total damping forces.

Thank You for the answer. Is there indirect way to obtain these values ? Have you recognized issue related to this topic ?

Many thanks in advance for replay.

Hello Michal,
Although I am not an expert on the field, I am not aware of any indirect method to calculate the energy dissipated only due to Rayleigh damping.
