Abstract: Because the vertical stiffness of two kinds of bearings of parallel base isolation structures are different,the axial forces will shift when the displacement of isolation layer increases under earthquake loading;and the dynamic characteristic of isolation layer appears strong nonlinearity.According to the character of axial forces shift between two kinds of bearings under earthquake loading,the resilience model of isolation layer considering the vertical force is given;and the calculating model ... More
