| 摘 要： | 石化行业某带壁板加热炉钢结构形式复杂，为评价其抗震性能，本文对整个结构进行了静力推覆分析。考虑了结构主体框架和侧墙壁板的共同作用，得到了多遇地震和罕遇地震性能点，并分析了性能点的变形形态和结构性态。结果显示多遇地震下结构均处于弹性，最大层间位移角为1／942，罕遇地震下结构进入塑性的范围不大，最大层间位移角为1／364。结论是该结构能够满足抗震规范中的“小震不坏，大震不倒”的性能要求。

| Abstract: | In order to evaluate the seismic performance of a steel structure with wall panel of heating furnace in petrochemical industry, static pushover analysis is done in this paper. In the analysis, the role of steel panel is taken into account. Performance points of frequent earthquake and rear earthquake are obtained. And deformation shape and structural state at the performance points are analyzed. The results show that the whole structure is in the elastic stage and maximum story drift angle is 1/942 under frequent earthquake while the range of the structure in plastic stage is very small and maximum story drift angle is 1/364 under rear earthquake. The conclusion can be drawn that the structure discussed in this paper could meet the requirements ＂no damage under small earthquake＂ and ＂no collapse under strong earthquake＂ specified in the seismic code. |
