More Information
Summary:The invention provides a cross-fault bridge space variability input place vibration simulation method based on a fault physical model and a pulse function. According to the method, a mixed method is adopted to simulate a seismic oscillation time history, a simulation method based on a fault physical model is adopted to simulate high-frequency seismic oscillation, a parameterized pulse function is adopted to simulate a low-frequency component, the two are filtered and then superposed to obtain the seismic oscillation time history, and finally, a conversion matrix considering the spatial variability of the seismic oscillation is adopted to simulate the seismic oscillation time history. The seismic action with the spatial variability characteristic is input ground vibration of non-uniform excitation of the cross-fault bridge. According to the method, a simulation method based on a fault physical model is combined with a mathematical pulse function of pulse effect parameterization, the seismic oscillation time hi
