Design and performance study of a novel isolation bearing
To improve the deformation capacity of composite rubber bearings with a friction damper and the displacement coordination of friction components,solid and parametric computa-tional models were established based on existing studies.The structure and internal force analysis of the novel composed isolation bearing were studied,and a solid finite element simulation of the friction damper and composed isolation bearing was performed using ABAQUS software.Based on the modeling and nonlinear time-history seismic response analysis of an isolated structure with conventional isolation bearing and the proposed combined isolation bearing,the relationship between the output and structural parameters of the composite bearing was deduced.The research results show that the parametric modeling method of the friction damper adopted in this study is accurate,and the novel composite bearing obviously reduces the tensile stress of the bearing and displacement of the isolation layer,improving the overturning resistance of the structure.The proposed simplified element for the friction damper can greatly improve the calculation efficiency of the finite element model.
