超高层建筑框筒结构的混凝土墙柱托换施工技术分析OA

The frame-tube structure,which consists of the outer steel frame and the inner concrete core,has been widely used in the design and construction of super high-rise buildings at present because of its high stiffness and low cost.With the increase of service life,the building structure needs to be reformed and strengthened,so the construction of concrete wall and column support is essential.Taking a super high-rise building project as an example,the paper elaborated the concrete wall column replacement scheme,and carried out the renovation and rein-forcement design based on the secondary force,and tested and analyzed the whole process of the replacement by using test instruments and sup-port system design,so as to verify the practical application reinforcement effect of the reinforcement method,with a view to further improving the construction quality of the project.
