Problems solved by technology

There are two types of double-steel plate shear walls: outer-wrapped steel plates and built-in steel plates. The outer-wrapped double-steel plates can also be used as formwork, which is convenient for construction. In the past, there were few studies on double-steel combined shear walls, and they were limited to straight cross-sections. There is no research on composite shear walls with double steel plates in channel section

Abstract

The invention relates to a composite steel plate shear wall, in particular to a groove-shaped steel plate shear wall with inbuilt round reinforcing cages and externally pasted steel plate supports and a construction method. The groove-shaped section adapts to the arrangement form of the shear wall in a building structure. As the inner sides of two steel plates are filled with concrete, buckling deformation of the steel plates can be effectively restricted, and the bearing capacity of the steel plates is improved. The concrete on the interior is double restricted by the steel plates on the two sides, cavity-dividing partition plates and the round reinforcing cages, so that the elastic-plastic deformation capacity and the ultimate compressive strength of the concrete are enhanced. The steel plate supports can fully play a role of diagonal draw bars and provide high resistant-lateral rigidity and a large bearing capacity for the shear wall. The flange parts of the shear wall with the groove-shaped section play a good role in restricting the web wall, so that the in-plane and out-plane bearing capacity of the composite shear wall is remarkably improved. Accordingly, the composite steel plate shear wall has the high bearing capacity and the good elastic-plastic deformation capacity.

Description

technical field [0001] The invention relates to a trough-shaped built-in round reinforcement cage and a steel plate shear wall supported by steel plates on the outside and a method thereof, which is mainly used in the field of energy dissipation and shock absorption control in building structures. Background technique [0002] With the development of society and the improvement of economic level, there are more and more high-rise buildings. Reinforced concrete high-rise buildings with large quantities and wide areas are usually composed of beams, columns, floors, shear walls and cores. The shear wall and the tube body composed of the shear wall are the core parts of the high-rise building's seismic resistance, and the seismic performance of the shear wall and the core tube plays a vital role in the safety and reliability of the high-rise building. Especially in recent years, there are more and more large and complex high-rise buildings pursuing individualization, and the re...
