摘要
Abstract
Based on the universal seismic damping spherical steel bearings,a new seismic damping spherical steel bearing is proposed,which uses the steel plate spring superimposed with seismic damping steel as the damping component.The energy dissipation capacity of Q295 steel was studied by means of monotonic tensile test and cyclic tensile test.The hysteretic and self-centering properties of seismic damping members of the bearings were analyzed by means of quasi-static test and numerical analysis.The new spherical steel bearing was applied to the grid structure to investigate its damping and energy dissipation capacity.The results indicate that the hysteretic curve of Q295 steel is full and has certain energy dissipation capacity.The new seismic damping member has a better energy dissipation performance and a certain self-centering capacity.Compared with the general elastic bearings,the new spherical steel bearings can dissipate part of the seismic energy,and thus further reduce the dynamic response of the structure.关键词
