Abstract

In order to obtain the floor response and floor acceleration response spectrum of seismic isolated museum, a finite element model of actual isolated museum was established.The model was verified through environment vibration tests.7 seismic time history curves were chosen to analyze the model.The difference between floor wave and seismic wave was analyzed through peak acceleration and frequency spectrum.The floor acceleration response spectrum was calculated through MATLAB and the design spectrum was fitted.The results show: the dynamic characteristics of FEM are in a good agreement with test values; The peak acceleration of 1—3 layers is lower than other layers.The frequency spectrum mainly ranges for low frequencies.The predominant frequency of floor wave is the natural frequency of structure.The difference between floor wave and seismic wave is great.The floor acceleration response spectrums is the result of earthquake working together with structure; The floor acceleration design response spectrum and mathematical formula were gotten.The seismic protection design method for exhibition tool and cultural relics was put forward.
