Fabricated steel structural self-restoring energy consuming supporting device

Abstract

The invention discloses a fabricated steel structural self-restoring energy consuming supporting device and belongs to the technical field of structural engineering. The fabricated steel structural self-restoring energy consuming supporting device includes an energy consuming system, a self-restoring system and a base. One side of the width of a stand column in the energy consuming system is full-length, and a hole is formed in the bottom of the stand column in order to make a cable pass through conveniently. A yellow brass plate is installed between two steel plates of the energy consuming system. The two steel plates are connected with each other through a bolt. The combination is used as the energy consuming system of the fabricated steel structural self-restoring energy consuming supporting device. A steel rope passes through the energy consuming system transversely through two end plates and the combination is used as the self-restoring system of the fabricated steel structural self-restoring energy consuming supporting device. The energy consuming system is connected with side bolts into one through a middle pin shaft and a lever mechanism is formed with respect to the pin shaft. In this way, lateral displacement on the bottom of the stand column is magnified on the top of the stand column. Meanwhile, deformation of the steel rope is low and increase of rope force is low.In addition, through the fixing effect of a pre-tightening piece, adjustment to the rigidity of the fabricated steel structural self-restoring energy consuming supporting device can be achieved so that when a building structure is used normally and in a ultimate state, requirements of resistant-lateral rigidity and energy consuming can be met.

Description

Technical field [0001] The invention designs a self-resetting energy-consuming support device for an assembled steel structure, which belongs to the technical field of structural engineering. Background technique [0002] As one of the natural disasters, earthquakes pose a great threat to human survival and development, and cause great economic losses. my country is located in the western part of the Pacific Rim Volcanic Seismic Belt and is one of the countries with the most severe earthquake disasters in the world. Therefore, earthquake resistance and disaster reduction of building structures is an important task. The method of resisting earthquakes has developed from the initial earthquake resistance to the current stage of earthquake reduction. The frame-support structure system is one of the commonly used double lateral force-resistant structural systems. The support structure can bear most of the horizontal shear force and reduce the horizontal displacement of the overall s...

Problems solved by technology

However, after the earthquake, when the energy-consuming core of the support is damaged, the entire support needs to be replaced, and the purpose of repairing the support by replacing only the core mechanism that consumes energy cannot be achieved. Not only is the construction inconvenient, but also a waste of steel, and the repair cost is also high. And the arrangement of supports affects the arrangement of doors and windows

However, the deformation of the cable in the cable-supported structure is too large, the cable force increment is large, and the structure cannot produce enough horizontal displacement to meet the requirements of the seismic code for ductile structures.
