Composite tension-compression energy dissipation brace locked by lead dots

Abstract

The invention belongs to the field of vibration control of a building structure, and particularly relates to a composite tension-compression energy dissipation brace locked by lead dots. The compositetension-compression energy dissipation brace comprises connection plates, connection plate screw holes, foamed aluminium energy dissipation plates, tension-compression supporting energy dissipation steel plates, tension-compression sharing energy dissipation mild steel plates, end part supporting energy dissipation steel plates, energy dissipation ribs, internally formed round holes, lead dot holes, extrusion energy dissipation materials and the lead dots; the composite tension-compression energy dissipation brace locked by the lead dots is formed by the surrounding of the connection plates,the tension-compression supporting energy dissipation steel plates and the end part supporting energy dissipation steel plates. The composite tension-compression energy dissipation brace locked by thelead dots has the advantages and effects that under the action of horizontal tension and compression, a plurality of tension-compression sharing energy dissipation mild steel plates can be coordinated mutually to share a tension-compression stress, so that a supporting system has no obvious stress concentration phenomenon, the supporting system is reasonable in plastic distribution and the supporting system has a multi-directional energy dissipation effect; moreover, the supporting system has reasonable initial rigidity, and can meet the supporting bearing requirement when damping and dissipating energy.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, and in particular relates to a composite tension-compression energy-dissipating support locked by lead pins. Background technique [0002] Earthquake disasters are sudden and devastating, which seriously threaten the safety of human life and property. Nearly a thousand destructive earthquakes occur every year in the world, and a major earthquake can cause hundreds of billions of dollars in economic losses, resulting in hundreds of thousands of deaths or serious injuries. The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. When an earthquake occurs, ground vibrations cause the seismic response of the structure. For a building structure whose foundation is fixed to the ground, its response is amplified layer by layer along the height from bottom to top. Due to the excessive seismic response (acceleration, velocity o...
