主　　题：selective pallet racks base isolation friction pendulum bearing system cross-aisle direction 

摘      要：The concept of base isolation for storage racks is still a developing subject and has not been addressed in the recently updated seismic codes for storage *** friction pendulum bearing system(FPS)generates a natural period independent of the structure s seismic *** property makes FPS an ideal choice for isolating rack structures since merchandise may be placed on the racks in several possible *** results of a comprehensive parametric study aimed at evaluating the seismic performance of a four-shelf,two-bay selective pallet rack isolated with FPS is presented in this *** influence of radius of curvature of the FPS,seismic mass,and mass irregularity on the rack s seismic response is *** effect of variation of the coefficient of friction due to axial loading is studied by choosing friction values from two distinct friction characterization *** coefficient of friction calculated from these studies shows mild and significant variations,respectively,for the whole range of static axial loads expected on the isolator,and from different pallet mass arrangements *** optimum radius of curvature and the appropriate range of friction coefficient,for the defined range of static axial loads,to attain a desirable seismic performance are determined.
