中文摘要	动力弹塑性时程分析是目前预测结构地震响应最准确的数值方法。为获得某石化加热炉钢结构在罕遇地震下的真实反应,本文对其进行了动力弹塑性时程分析。考虑双向地震作用,对结构输入3组调幅后的地震波,考察结构整个过程中的底部剪力、楼层位移和结构损伤情况。结果显示不同工况下,剪重比为24%~40%,最大层间位移角为1/620,结构整体进入塑性的部分不多,塑性铰只出现在梁上和极少数柱脚处。该结构始终处于直立状态,能够满足"大震不倒"的抗震设防目标要求。; Elasto-plastic time history analysis is the most accurate numerical method to predict earthquake response of structures. In order to obtain the real response of a steel structure of heating furnace in petrochemical industry under rear earthquakes,time history analysis is carried out in this paper. Three earthquake waves with amplitude modified are input into the structure in two directions,and then shear force at the base,story drift and structural damage in the whole process are investigated. The results show that under different load cases,shear-to-weight ratio is 24% ~ 40%,and maximum story drift angle is 1 /620. During the whole process,the part of the structure in plastic stage is very small and the plastic hinges appear only in some beams and at a very small number of column feet. The structure is always standing and could meet the seismic requirement of "no collapse under severe earthquakes".
