Description
技术领域 technical field

The disadvantages of human uncontrollable factors and other aspects have been popularized and applied in engineering practice.
ZL201210054809.3公开了一种预制钢管混凝土边框剪力墙，其充分利用了钢管混凝土边框与混凝土剪力墙的优势结合，但该种剪力墙受限于钢管混凝土边框，如果建筑高度过大或剪力墙体过宽，势必导致钢管混凝土边框与混凝土墙体之间的协调受力变形过大，那么也就相应提升了协调构造措施，导致其成本效率的下降。 ZL201210054809.3 discloses a prefabricated steel tube concrete frame shear wall, which makes full use of the combination of the advantages of the steel tube concrete frame and the concrete shear wall, but this kind of shear wall is limited by the steel tube concrete frame, if the building height is too large or If the shear wall is too wide, it will inevitably lead to excessive deformation of the coordinated force between the CFST frame and the concrete wall, and then the coordinated construction measures will be improved accordingly, resulting in a decrease in its cost efficiency.
