Energy consumption support with replaceable energy consumption parts at two ends

Abstract

The invention discloses an energy consumption support with replaceable energy consumption parts at the two ends. The energy consumption support comprises two energy consumption units and a supportingunit as a stress framework. The two energy consumption units are arranged at the two opposite ends of the supporting unit respectively. Each energy consumption unit comprises a hollow high-strength steel column and a low-yield-point steel component arranged in the high-strength steel column. The supporting unit can provide sufficient bearing capacity and rigidity, the low-yield-point steel components serve as the materials of the energy consumption units, the material mechanical performance of high-strength steel is brought into full play, and guarantees are provided for yield energy consumption of the low-yield-point steel components. In moderate and small earthquakes, main stress damage parts are the energy consumption units at the two ends of the supporting unit, and the structure can be rapidly replaced and repaired after the earthquakes; in large earthquakes, the lateral supporting unit in the energy consumption support may be damaged under the effect of the earthquakes, and the structure can be rapidly repaired and reinforced by replacing the lateral supporting unit after the earthquakes.

Description

technical field [0001] The invention relates to the technical field of building shock absorption, in particular to an energy-dissipating support with replaceable energy-dissipating components arranged at both ends. Background technique [0002] Buildings built in seismic fortification areas must consider the seismic performance of the structure, and the wind resistance performance must also be considered during structural design. The steel support frame structure has light weight, and the seismic force on the structure is relatively small under the action of the earthquake, so it is widely used. It is used in multi- and high-rise structures in seismic fortification areas. However, the traditional steel support is prone to buckling when it is compressed under strong earthquakes, which can easily cause damage or failure of the support itself or the connection. , reducing the seismic capacity of the structure. Therefore, some foreign researchers have developed a component tha...
