Abstract

The invention relates to a high-performance support component based on self-reset energy dissipation. The high-performance support component comprises a self-reset energy dissipation part (3) and main body support cylinders respectively mounted at two ends of the self-reset energy dissipation part (3), wherein end joints are further arranged on the main body support cylinders; and the self-reset energy dissipation part (3) comprises an outer cylinder (32) and a piston guide rod (31), a viscous damper cavity (33) and a shape memory alloy ring spring group cavity (34) are further arranged in the outer cylinder (32), one end of the piston guide rod (31) sequentially penetrates through the viscous damper cavity (33) and the shape memory alloy ring spring group cavity (34), the other end is fixedly connected with one main body support cylinder, and the other main body support cylinder is further fixedly connected to the outer cylinder (32). Compared with the prior art, the high-performance support component integrates important anti-earthquake functions such as lateral load resistance, bending resistance, self-reset and wide frequency domain energy dissipation, the disadvantage of insufficient energy dissipation of a viscous damper under low frequency and high temperature is improved, and the high-performance support component does not need to be replaced after the earthquake.

Description

technical field [0001] The invention relates to the field of anti-seismic and shock-absorbing technology of structural engineering, in particular to a high-performance support member capable of providing energy consumption in a wide frequency range during an earthquake and self-resetting after an earthquake. Background technique [0002] The bracing system is one of the important components of a building structure against lateral forces including earthquake and wind loads. The current design goals usually allow elastic-plastic deformation of supports under large earthquakes, so higher requirements are placed on the deformation performance and bearing capacity of support members and their connection parts. Although traditional flexible supports can provide lateral stiffness through tensile strength, they gradually fail due to continuous yielding during earthquakes, resulting in a void effect and losing energy dissipation capacity. At the same time, the plastic deformation of...
