基于有限元软件ABAQUS的砌体结构地震破坏模拟 冯学刚1戴君武1王艳茹2 (1．中国地震局工程力学研究所，哈尔滨150080；2．温州大学，温州325035) 摘要：本论文利用ABAQUS软件模拟砌体结构在地震作用下结构反应。充分考虑各种模拟 砌体结构方法的优缺点，文中采用整体式模型，将砌体结构墙体视为各向同性的均匀连续体， 并采用Concrete DamagedPlasticity材料模型来模拟砌体结构材料特性，输入从汶川地震强 震数据库中选取的地震动。分析结果表明，文中模型很好地模拟出了砌体结构在地震作用下 的破坏特征 关键词：砌体结构；有限元模拟；地震响应分析；ABAQUS Seismic of based simulation structures damage masonry OHfiniteniteelementelementsoltware nOSUOABA,rawtfos U Dai Yanru2 Feng JunwulWang Xuegan91 of (1．Institute Mechanics，ChinaAdministration， Engineering Earthquake Harbin 325035，China) 150080，China；2．WenzhouUniversity，Wenzhou Abstract：TheFEMsoftware iSusedtOsimulatetheseismic ofmason- ABAQus performance structureinthis intothe and ofsimulation ry paper．Takingadvantagedisadvantage methods， the modelisutilkedtosimulate of wallisre- seismic structure．码e integral damagemasonry as theconcrete materialmodelis continuum；and gardedisotropicevenly damagedplasticity tosimulatethematerialcharacteristicsofthestructur已ExactionfromWenchuan adopted motiondatabaseisusedinthis simulation．Theresultsshowthat earthquakeground analyzing the modelwellreflectsa featureofa structu
