Embodiment Construction
[0022] Below in conjunction with accompanying drawing, the embodiment of this patent is described in detail.
[0023] Such as Figure 1~6 As shown, a double-layer steel plate composite shear wall reinforced with open corrugated web includes the following components.
[0024] 1——steel plate shear wall unit;
[0025] 2 - Outer steel plate;
[0026] 3——Open corrugated web;
[0027] 4 - tie rod;
[0028] 5 - filled with concrete.
[0029] Such as Figure 1~4 As shown, the device is welded by several steel plate shear wall units 1 to form a double-layer steel plate shear wall, and then concrete 5 is poured between the steel plates to form a double-layer steel plate combined shear wall with corrugated web reinforcement with openings. The steel plate shear wall unit 1 is composed of two outer steel plates 2, a corrugated web 3 with holes, and a tie bar 4; At the trough of the web, two steel plates at the front and rear are tied; each steel plate shear wall unit 1 is connected ...

The invention relates to a double-layer steel plate composite shear wall stiffened with punched corrugated webs, and belongs to the field of structural engineering. The steel plate composite shear wall is composed of a double-layer steel plate shear wall formed by welding a plurality of steel plate shear wall units, and integrated-poured concrete. According to the double-layer steel plate composite shear wall, based on the idea of improving the buckling load of outer side steel plates and strengthening the combination effect between the outer side steel plates and inside-poured concrete, the outer side steel plates are subjected to stiffening and detail restraint by arranging the punched corrugated webs and tie bars, and thus, the out-plane stiffness and the bearing capacity of the composite shear wall are greatly improved. In order to achieve the structure and the idea that factory machining and transporting are facilitated and assembling requirements are met, the steel plate shear wall is divided into the multiple steel plate shear wall units, the arrangement mode is more flexible, construction is convenient and quick, and the quality is easy to ensure.
Description
technical field [0001] The patent relates to a double-layer steel plate composite shear wall reinforced with corrugated webs with openings, which belongs to the field of structural engineering. Background technique [0002] With the increasing height of buildings, horizontal loads have gradually replaced vertical loads as an important control factor in the design of high-rise buildings. Traditional lateral force-resistant components can no longer meet the needs of high-rise buildings for energy dissipation and horizontal bearing capacity. The steel plate shear wall structure is a new type of lateral force-resisting structural system developed in the 1970s. It has become a structure favored by many designers because of its extremely high bearing capacity, stable energy dissipation capacity and good ductility. [0003] The steel plate-concrete composite shear wall is a new type of lateral force resistance system developed on the basis of the steel plate shear wall. Composite ...
