摘要: 对某11层框架剪力墙结构住宅工程结构检测时,发现第7层部分墙柱和第8层部分梁板混凝土强度严重不足。通过采用斜向钢支撑荷载转移法实现对中柱的托换,采用剪力墙两端分批凿除后再浇捣实现对剪力墙的托换,采用增加截面法对边柱进行加固,使建筑物经托换和加固后能满足国家有关规范的要求。Abstract: The detection of a 11-layers frame shear wall structure shows that the concrete strength of the seventh partial wall columns and the eighth partial beam and floor plate in that building are very low.For meeting the related nantional standards and avoiding demolishment of the building,the underpinning and strengthening methods are used,with which the loads of center column are underpined by the diagonal steel strut and the cross-sectional areas of side pillar are strengthened,both ends of shear wall are chiseled in turn and then concrete is poured again.
