Problems solved by technology

[0008] The purpose of the present invention is to overcome the shear buckling of thin steel plate shear walls in the prior art, and the commonly used central support anti-lateral force system is easy to lose most of the bearing capacity due to instability, greatly reducing ductility, structural deformation capacity, and consumption. In order to solve the problem of weak performance, a steel plate-steel support composite anti-lateral force component and a beam-column structure using the component are provided. The technical scheme provided by the invention is used to constrain the out-of-plane deformation of the steel plate through the steel support so as to avoid the hysteresis curve "Pinch together"; at the same time, the tension field of the steel plate is used to constrain the extreme point instability that often occurs in the structural plane of the compressed steel support, so as to obtain a composite lateral force-resistant member with excellent seismic performance, and the seismic energy dissipation capacity is greatly improved.

Abstract

The invention discloses a steel plate-steel support combined lateral force resisting member and a beam column structure applying the same and belongs to the technical field of lateral force resisting members in structural engineering. The steel plate-steel support combined lateral force resisting member comprises a steel plate, a steel support integrally connected with the steel plate, wherein the steel plate is in a shape like a Chinese character 'tu', the steel support comprises two portions respectively arranged on two sides of the steel plate, bolt holes are arranged on the steel support at intervals, bolt holes are also arranged at corresponding positions of the steel plate, the two portions of the steel support are respectively connected with the steel plates through high-strength bolts, the steel support is arranged in a V-shaped mode and used for providing a part of axial tension resisting and compression resisting capacity of the lateral force resisting member. The main purpose is that the steel support is utilized to constrain deformation outside a plane of the steel plate so as to avoid 'pinch' effect of a hysteretic curve, a pulling force field of the steel plate is utilized to constrain a phenomenon that an extreme point of the compressed steel support in a structural plane is often unstable, and accordingly the lateral force resisting member with excellent anti-seismic property is obtained.

Description

technical field [0001] The invention relates to a lateral force-resistant member and a beam-column structure using the same, more specifically, to a steel plate-steel support composite lateral-force-resistant member and a beam-column structure using the same. Background technique [0002] Earthquake is the biggest natural enemy of buildings and a great threat to human existence. The dual seismic system in the steel structure often uses steel plate shear walls or steel supports as the first line of seismic defense to resist the horizontal action of small and moderate earthquakes. Under the action of a large earthquake, on the one hand, the steel plate shear wall or steel support consumes seismic energy through its own buckling and yielding, and acts as a "fuse" to protect the safety of the steel frame bearing gravity load; on the other hand, due to its own stiffness The degradation reduces the earthquake response, so that the steel frame as the second anti-seismic defense li...
