Steel frame building wall with damping joints and construction method thereof

Abstract

The invention discloses a steel frame building wall with damping joints and a construction method thereof. The steel frame building wall with the damping joints comprises a wallboard, a steel frame beam and the damping joints. The damping joints comprise upper joints and lower joints. Each upper joint comprises a Z-shaped steel plate, a first round hole is formed in one end of each Z-shaped steel plate, a long round hole is formed in the other end of each Z-shaped steel plate in the width direction of the Z-shaped steel plate, each first bolt penetrates through the corresponding first round hole and is connected with the upper surface of the steel frame beam, and each second bolt penetrates through the corresponding long round hole and is connected with the upper end face of the wallboard. Each lower joint comprises a steel bracket, each steel bracket is connected to the upper surface of the steel frame beam and is provided with a second round hole, and each third bolt penetrates through the corresponding second round hole to be connected with the lower end face of the wallboard. Each third bolt is sleeved with a spring. Compared with the prior art, the steel frame building wall with the damping joints is good in damping effect, economic losses after earthquakes are reduced, and fast repair can be achieved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a steel frame building wall with damping nodes and a construction method thereof. Background technique [0002] The walls of steel frame buildings generally include steel frame beams and wall panels, and the connection nodes between wall panels and steel frame beams are key factors in the seismic design of steel frame buildings. Under earthquake action, the wall panel is a displacement-sensitive non-structural component inside the plane, and an acceleration-sensitive component outside the plane. Because the in-plane ductility of wall panels is generally lower than that of steel frame beams, if the connection nodes between wall panels and steel frame beams are treated as in-plane rigid connections, under the action of coordinated deformation with steel frame beams, wall panels usually When the interstory displacement of the beam is not large, in-plane cracking damage or even collapse ...

AI Technical Summary

Problems solved by technology

Rigid connection nodes are usually used in the existing technology, and wall panels contribute greatly to the stiffness and bearing capacity of steel frame beams. On the one hand, it will increase the overall stiffness of the structure, change the stiffness and bearing capacity distribution of the structural system, and may have adverse effects on the structure's seismic resistance ; On the other hand, it is also easy to cause the wall panels to be damaged before the steel frame beams, resulting in economic losses
