Supporting building with tension and compression reversing characteristic and assembling method thereof

Abstract

The invention discloses a supporting building with a tension and compression reversing characteristic and an assembling method thereof. The supporting building comprises end plates making contact witha wallboard, supporting rods penetrating through the end plates and dampers positioned at two sides of the supporting rods. Two ends of the upper end plate and two ends of the lower end plate are respectively bent by 45 degrees, so that the ends of the upper end plate and the lower end plate are parallel to a steel beam and a steel column, and holes are formed in the end plates so that the supporting rods and SMA elements can pass through; the supporting rods are provided with grooves and opposite-penetrating bolt holes cooperative moving blocks positioned on the inner sides of the end platesare welded on the grooves of the supporting rods, and the supporting rods drive the end plates to move through the cooperative moving blocks when being pulled or pressed; the SMA elements are pulledas the end plates move. The dampers consist of energy dissipation plates with circular arc-shaped holes and connecting plates with bolt holes at two ends. The supporting building with the tension andcompression reversing characteristic has the characteristics of simple structure, stable energy dissipation, convenience in installation and the like. When the supporting rods are pulled or pressed, the energy dissipation self-resetting dampers have the tension and compression reversing characteristic and always enable the SMA elements to be pulled so as to provide energy dissipation and self-resetting.

Description

technical field [0001] The invention belongs to the field of supporting structures in buildings, and relates to a supporting building with tension-compression reversing characteristics and an assembly method thereof. Background technique [0002] Steel structures have significant circular economy characteristics throughout the life cycle of raw material production, construction, use, dismantling and recycling, and meet the requirements of energy saving, land saving, water saving, material saving and environmental protection. One of the most ideal structural systems. [0003] The traditional staggered truss structure is prone to instability and failure when the support is under pressure, and the structural bearing capacity and energy dissipation capacity will be significantly reduced. The buckling-constrained support fully develops the plasticity of the core components to provide energy dissipation, but the structure will retain significant residual deformation after a stron...

AI Technical Summary

Problems solved by technology

A reasonable combination of low-yield point steel dampers and SMA components can achieve the goal of energy dissipation and self-resetting balance. Therefore, applying the above two components to the staggered truss structure makes it have good energy dissipation and self-resetting characteristics.
