Description
Technical Field
The invention relates to the technical field of shear walls, in particular to a concrete filled steel tube column combined shear wall and a construction method.
Background
The traditional reinforced concrete wall is used for high-rise buildings due to high transverse rigidity and strength, but the reinforced concrete wall shows lower ductility and limited deformability under high axial compression ratio, and two methods are mainly adopted for solving the problem of low ductility and deformability of the reinforced concrete wall in the high-rise buildings in the traditional way: (1) limiting the axial compression ratio, which is commonly adopted in the existing earthquake-resistant design specifications, wherein the specifications stipulate that the design axial compression ratio of a high-rise building should be less than 0.5, but the adoption of the method can cause the size of the wall to be increased, and particularly in the lower layers of the high-rise building, the increased size of the wall occupies a large amount of available building area; (2) changing the configuration and reinforcement of the wall, particularly the boundaries of the wall, can be accomplished by providing closely spaced transverse reinforcement bars (or stirrups) that secure the concrete to provide the concrete with sufficient load bearing capacity, however, the core concrete does not provide its full load bearing capacity due to the "arching effect" that occurs when the concrete is compressed.
At present, in the reinforced concrete wall of a high-rise building, the comprehensive performance of high-strength concrete is better than that of common-strength concrete because it can: (1) reducing component size by increasing strength, weight ratio, and stiffness of the structure; (2) the carbon content of the building is reduced, and the sustainability of the material is enhanced; (3) the maximum utilization rate of the building area is realized. However, the application of high-strength concrete in reinforced concrete walls has been very rare due to the brittleness of the high-strength concrete. Although ductility may be improved by providing confining pressure by installing stirrups, its effectiveness decreases as the strength of the concrete increases. Therefore, when the concrete strength is more than or equal to 80MPa, in order to restore the ductility level which can be used for actual wall construction, the content of the needed stirrups is increased, and the pouring quality of the concrete cannot be ensured. Therefore, the use of high-strength concrete in conventional reinforced concrete walls is not suitable. In addition, when the stirrup of the traditional reinforced concrete wall is buckled, the constraint action on the concrete core is obviously reduced, so that the concrete is seriously peeled off, and the traditional concrete wall cannot bear larger axial load acting on the top of the wall. How to improve the use of high-strength concrete in a high-rise building wall, namely, how to improve the mechanical properties of the wall, such as earthquake resistance, pressure bearing capacity, deformability and the like, when the concrete strength exceeds 80MPa in the actual wall construction, is a problem to be solved urgently.
