static equivalent VS time history analysis
static equivalent VS time history analysis
(OP)
i designed 8 story rigid frame building using static equivalent seismic load as lateral load
when i did linear time history analysis as lateral load (SE not used anymore), some of its members are overstress.
somebody told me that SE is always larger than THA and it's impossible that my members are overstress
is there possibility that THA is larger than SE in member internal forces?
i'm pretty sure that my step is based on ASCE 7-10
thank you

RE: static equivalent VS time history analysis
Also, the SE is equivalent to the first mode of vibration, while a THA is probably retrieving higher modes too.

I've seen it a few times.
