Shock Absorption And Vibrati On Serviceability Analysis Of Friction Pendulum Bearing On A Connected Structure

The basic principle of friction pendulum bearing(FPB) is presented,FPB is used in corridor structure models. modal analysis and spectrum analysis and time history analysis of FPB isolated and non-isolated corridor structure are conducted in SAP2000. And making a compare about the corridor structure vibration serviceability under the walking and running incentive. modal analysis and spectrum analysis about the main structure are conducted in SATWE and MIDAS BUILDING.. the influence of corridor or non-corridor structure on the main structure is compared. The results show that:1) Installing FPB can effectively control the seismic response of structure,including corridor structure X,Y,Z displacement,acceleration, base shear, etc. internal forces of structural members are reduced. The hysteretic energy dissipation behavior of FPB under rare earthquake is performed into fuller play than that under conventional earthquake,the decreasing amplitude of structural response is obvious,and the seismic reduction effect is more ideal.2) The comfort of the corridor structure which installs FPB under the walking and running incentive can satisfy the requirements, the influence of corridor structure under the running incentive is more obvious.3) Comparing the period of the first six, shear-weight ratio, stiffness-weight ratio, the maximum displacement between layers, displacement ect on the main structure shows that the above information of the main structure by increasing the corridor structure is not significant.
