摘　　要：随着国家抗震设防标准及区域抗震设防要求的提高,多年前建造的75版标准图集7度设防工业厂房可能存在于现行国家抗震设防标准的7度、8度或者9度抗震设防地区,从震害估计、结构加固角度出发,工程师需要了解此类结构在不同抗震设防地区的抗震性能。借助ABAQUS软件,考虑材料的实际力学性能,采用数值模拟方法对地震作用下75版标准图集7度设防工业厂房进行了弹塑性动力时程分析,基于分析结果,对该类厂房在各抗震设防烈度下的抗震性能进行了评估,对在8度(0.20g)以上(含)抗震设防地区结构加固的必要性及方法进行了讨论,提出了相应的结构抗震加固对策。Due to the improvement of national seismic fortification standards and regional seismic fortification requirements,the industrial factory building built many years ago may exist in areas with 7-degree,8-degree or 9-degree seismic fortification according to the current national seismic fortification standards.From the perspective of earthquake damage estimation and structural reinforcement,engineers need to understand the true seismic performance of such structures.By ABAQUS software and considering the actual mechanical properties of materials,this numerical simulation method was adopted to analyze the elastic-plastic dynamic time-history of the 7-degree fortification industrial factory building in the 75th edition standard under earthquake action.Based on the analysis results,the seismic performance of this type of industrial factory building under various seismic fortification intensities was evaluated.The necessity and method of structural reinforcement in 8-degree(0.20g)or above(including)seismic fortified areas was discussed.The seismic reinforcement measures for the structure were proposed.
