T-shaped steel reinforced welding connection joint

Abstract

The invention discloses a T-shaped steel reinforced welding connection joint, and belongs to the technical field of steel structure joint connection. T-shaped steel is reinforced by welding connection, T-shaped steel connecting ends are connected again by the aid of a right-angle energy dissipation connection steel plate, a main energy dissipation connection steel plate and a lead dot according tostructural design, the T-shaped steel can drive a branch energy dissipation connection steel plate and the main energy dissipation connection steel plate to dissipate energy in pull-pressing, energydissipation efficiency is remarkably improved, pull-pressing energy dissipation effects are more sufficient, the joint has enough bearing capacity and proper joint stiffness, so that the connection joint has a certain initial stiffness and a certain anti-seismic property, the characteristics of low anti-seismic capacity and poor energy dissipation capacity of a joint caused by only welding connection of traditional T-shaped steel are changed, seismic response can be decreased, the T-shaped steel is connected by the aid of a shape memory alloy wire, so that a whole structure has good self-resetting capacity after small displacement, and safety and reliability of the connection joint are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of steel structure node connection, in particular to a reinforced welded connection node of T-shaped steel. Background technique [0002] Steel structure connection generally refers to the interconnection between steel structure members or parts. Steel structure connections are usually welded, bolted or rivet connected. There are ordinary bolted connections and high-strength bolted connections in bolted connections. Ordinary bolt connections were used the earliest, starting from about the middle of the 18th century. In the 1920s, rivets were used. In the second half of the 19th century, welded joints appeared again. Since the middle of this century, high-strength bolted connections have been developed, which can ensure that the nodes have sufficient bearing capacity and appropriate node stiffness to achieve the transfer of internal forces at the nodes, but the seismic performance of the connected nodes i...

AI Technical Summary

Problems solved by technology

The material of the steel structure connection joints currently developed is easy to become brittle, resulting in residual stress, residual deformation, and welding defects, which have an adverse effect on the fatigue and stability of the steel structure. It depends more on the skill level of the welder, and the inspection workload is high when the quality inspection requirements are high. Larger and poor seismic performance, so the energy-dissipating manufacturing process and energy-dissipating capacity of some steel structure connection nodes still need to be further improved
