Abstract
This study investigates the seismic performance of a fully indoor semi-rigid steel-structured substation equipped with Lead-Rubber Bearings(LRBs)for seismic isolation through a shaking table test.A 1∶3 scaled model was adopted,and the model structure was designed in compliance with the similarity theory.Shaking table tests were conducted to obtain the acceleration responses of the structure and electrical equipment,as well as the displacement data of the supports.Test results demonstrate that the LRB isolation bearings can effectively extend the natural vibration period of the structure,avoid the dominant period in seismic waves,and reduce structural responses.Additionally,the damping capacity of the structure is significantly enhanced,thereby achieving a favorable seismic mitigation effect.However,the acceleration amplification effect of electrical equipment is relatively notable,with the maximum acceleration amplification factor reaching 6.76.This indicates that special attention must be paid to the safety and stability of electrical equipment.In particular,under the action of near-field seismic waves with pulse effects,the impact of seismic waves on the peak acceleration of electrical equipment becomes more pronounced.This research provides an experimental basis for the study on seismic isolation and mitigation of fully indoor semi-rigid steel-structured substations.关键词
