Truss type steel-reinforced concrete framework side node with energy dissipation device

Abstract

The invention relates to a truss type steel-reinforced concrete framework side node with an energy dissipation device. The steel skeleton in a beam is a truss type steel skeleton, which comprises vertical members, chord members and diagonal members. T-shaped profile steels are arranged on the upper and the lower parts of the beam to serve as the chord members, and are connected through angle irons, so that a truss type steel skeleton concrete beam member is formed. The vertical members and the chord members on the ends of the beam and in the core area of the node form a rectangular structure, the diagonal members are crossed, and are welded between the upper chord members and the lower chord members, the truss type steel skeleton extends into a column, and the length of the extending end is 0.9 times as the width of the section of the column in the direction. The ductility, equivalent viscous damping coefficient he and average energy dissipation coefficient Beta of the truss type steel-reinforced concrete framework side node with the energy dissipation device disclosed by the invention are remarkably increased in comparison with the ductility, equivalent viscous damping coefficient he and average energy dissipation coefficient Beta of reinforced concrete nodes. The truss type steel-reinforced concrete framework side node with the energy dissipation device has good structural seismic resistance and energy-dissipating capability.

Description

1. Technical Field [0001] The invention relates to a steel-reinforced concrete structure in the field of structural engineering in the field of civil engineering, a node component in the research direction of structural earthquake resistance and structure control, and specifically to a truss-type steel-reinforced concrete frame side node with energy dissipation devices. 2. Background technology [0002] Frame structure is one of the most commonly used structural forms in construction engineering. According to different building materials, frame structures are usually divided into reinforced concrete frame structures, steel-reinforced concrete frame structures and steel frame structures. Frame nodes are an important part of effectively connecting frame beams and column members to make them work together. They play an important role in transmitting and distributing internal forces and ensuring the integrity and ductility of the structure. Reasonable design nodes can effectively dis...

Problems solved by technology

However, the amount of steel used in the structure is large, and the bonding force between the steel frame and the concrete is poor. It is necessary to add special anchor bolts to improve the bonding performance between the steel frame and the concrete. and construction are more complex
