Abstract: Under strong earthquake, the possible uplift-slip of the nuclear island common raft has a significant impact on the structural stress state. Refinedly simulating the contact state on the raft-soil interface and analyzing the dynamic behaviors of the structure-interface-soil as a whole are helpful to clarify the influence mechanism of uplift-slip effects on the seismic response of the structure. By applying the penalty function method to simulate the contact mechanical behavior between the raft a... More
