The differences and change rules of the structural response were studied generally under multiple support excitation and simple support excitation from two aspects,i.

Elastoplastic seismic response and strength failure analysis of Laoshan bicycle-gymnasium for the Olympic games are studied under multiple and simple support excitation.

According to the calculation of element reliability index of space lattice structures with different spans and different forms under multiple support excitations or simple support excitation,the differences of dangerous elements and their distribution law are thoroughly analyzed involving the effects of structural span and apparent velocity.

Seismic response analysis of soil layer under uniform excitation;

Furthermore,the seismic response under traveling seismic wave excitations is compared with that under uniform excitations,the result indicates that:the traveling seismic wave excitation can increase,or decrease the seismic response of the transmission tower-cable system,which depends on both the traveling-wave velocity and the ground motion characteristic;the traveli.

Based on both geometrical nonlinearity and material nonlinearity,seismic response of long-span single layer cylindrical reticulated shell under multi-support excitations and uniform excitations is studied,and comparison is also made.
