| 摘 要： | 利用Arcgis软件的分析功能,统计和分析了乌鲁木齐活断裂带规定避让区内的建筑物类型和结构特点。再采用大型有限元分析的Ansys软件,对近断层建筑进行非线性地震反应分析,得到三种地震波输入时顶层水平位移时程曲线、加速度时程曲线,并对不同地震波输入下的建筑结构反应结果进行了分析,分析结果表明:和框架结构相比,多层砖混结构在同样地震波输人情况下,水平x方向弹性位移要小很多,且达到最大值时刻也要滞后,但是在竖直y方向位移却要远远大于框架结构房屋的y方向位移。并对断裂两侧不适宜盖哪些建筑提出建议。

| Abstract: | By using Arcgis software,the types and structural characteristics of the buildings in the avoiding zone near the active fault in Urumqi are analyzed.Nonlinear seismic response analysis of the buildings is also carried out by using the finite element software of Ansys so that to obtain the time-dependent curve of horizontal displacement and time-dependent curve of roof acceleration when three kinds of seismic waves are input.The results can be stored in database for reference to the existing project's strengthening and the newly building's aseismatic design. |
