摘要
某在建框筒结构部分剪力墙强度不足,对比了几种常用的加固方法,最适合本工程的加固方法为混凝土置换法;根据工程实际情况提出了混凝土置换施工的难点;计算出了需置换混凝土的剪力墙的竖向力,提出了用槽钢形成格构式支撑的方式进行支撑,并根据各墙肢所受竖向力及格构支撑的承载力,计算出了各墙肢所需支撑数量。
The strength of a part of shear walls of an under construction frame-tube structure residence was insufficient,several common reinforcement methods have been compared,the most suitable strengthening method for this project was concrete displacement;According to the actual situation of the project,the difficult points have been presented;The vertical force of the shear walls which need to replace concrete has been worked out,the way with channel steel to form latticed steel-structural brace to support has been presented,and according to the vertical force of the shear walls and the bearing capacity of the latticed steel—structural brace,the number of the braces of each wall has been worked out.
