Steel plate shear wall structure with semi-wrapped concrete combination column and anchoring structure thereof

Abstract

The invention discloses a steel plate shear wall structure with a semi-wrapped concrete combination column and an anchoring structure thereof. The steel plate shear wall structure can effectively provide an anchoring effect of an edge constraint frame of the steel plate shear wall structure on a built-in steel plate, so that a sufficient and uniform tension field is formed, the anti-seismic property of the structure is fully exerted, the bearing capacity of the structure is higher, the hysteretic behavior is more stable, and assembling is easy. The steel plate shear wall structure comprises two double-C-channel-steel combined section columns, two double-C-channel-steel combined section beams and a built-in steel plate; each of the double-C-channel-steel combined section columns and each of the double-C-channel-steel combined section beams comprises two pieces of C-shaped channel steel arranged oppositely; the edge of the built-in steel plate is clamped between the two pieces of C-shaped channel steel arranged oppositely; the edge of the built-in steel plate is anchored and connected with the C-shaped channel steel through high-strength bolts; and concrete is poured into steel grooves of the two pieces of oppositely-arranged C-shaped channel steel of the double-C-channel-steel combined section columns, so that the semi-wrapped concrete combination column is formed.

Description

technical field [0001] The invention belongs to the field of building construction and structure anti-seismic, and in particular relates to a steel plate shear wall structure with a semi-wrapped concrete composite column and an anchoring structure thereof. Background technique [0002] The structural unit of the steel plate shear wall is mainly composed of three parts: the embedded steel plate, the vertical edge restraint member and the horizontal edge restraint member. The enlarged steel plate is prone to local buckling, and forms tension bands along the diagonal direction, and the bulging tension bands play the role of diagonal bracing, which improves the bearing capacity of the structure. [0003] The prerequisite for the steel plate shear wall structure to give full play to the seismic performance is that the steel plate buckles in a large area and forms uniformly distributed tension bands along the diagonal direction. The restraint frame provides sufficient anchorage f...

Problems solved by technology

[0003] The prerequisite for the steel plate shear wall structure to give full play to the seismic performance is that the steel plate buckles in a large area and forms uniformly distributed tension bands along the diagonal direction. The restraint frame provides sufficient anchorage for the built-in steel plates. However, the rigidity of ordinary steel edge columns is small, and the large earthquake center often buckles prematurely and fails, which causes more tension bands to act on the edge restraint beams, resulting in The steel plates near the restraint column cannot be fully utilized, thus forming an "insufficient tension field", the effective anti-side area of ​​the structure is reduced, and the energy dissipation performance is difficult to fully exert

[0004] The built-in steel plate, as an important energy-dissipating component, is often connec
