static equivalent VS time history analysis

[nabildhiyaulhaq]

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

If you are modelling the diaphragm flexibility you may have a different story shear force when comparing to SE assumptions.
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.
