摘要:
针对2008年“5·12”汶川地震中砌体结构教学楼大量倒塌这一惨痛教训,总结了实际工程中砌体结构房屋的整体性缺陷以及常用的加固方法;采用通用有限元分析软件ANSYS建立了一个典型砌体结构教学楼(预制多孔板装配式楼盖)的数值模型,施加经修正后的汶川地震波,并利用有限元时程分析方法,分析了使用现浇混凝土叠合层加固前后该砌体结构教学楼在汶川地震波下的响应,重点对比了结构的模态、变形以及应力水平。结果表明:现浇混凝土叠合层可以使墙体的变形得到有效约束,横墙和纵墙的加速度基本一致,墙体变形以及最大应力均得到减小,这说明增设现浇混凝土叠合层是一种有效的加固预制板楼盖的方法。
Abstract:
Considering a great number of buildings collapsed in “5·12” Wenchuan Earthquake in 2008, several integrity defects of existing masonry structures and common strengthening methods were summarized. A general finite element analysis software ANSYS was used to build an numerical model of a typical masonry teaching building with precast reinforced concrete (RC) slabs, and Wenchuan earthquake wave was input on this model. By applying finite element time-history analysis method, the responses under seismic waves for masonry teaching buildings strengthened by cast-in-place RC layer before and after strengthening were analyzed, moreover, the structural modal, deformation and stress level were mainly compared. The results show that cast-in-place RC layer will effectively restrain the deformation of walls, thus the accelerations of cross and longitudinal walls match well, and the deformation and maximum stress of walls are reduced. This indicates that adding castinplace RC layer is an effective method for strengthening precast RC slabs.
