Assembled steel structure self-restoration module based on support energy dissipation

Abstract

The invention relates to an assembled steel structure self-restoration module based on support energy dissipation. The assembled steel structure self-restoration module comprises vertical edge components, transverse edge components, supporters and hinging posts, wherein a plurality of back tensioning prestress steel stranded wires are arranged along the two transverse edge components and are anchored on the outer side flanges of the two vertical edge components, so that a prestress framework is formed; the inner sides of the two vertical edge components are provided with the two hinging posts, and end plates are arranged at two ends of the two vertical edge components and are connected with the flanges of the two transverse edge components (the upper transverse edge component and the lower transverse edge component) through high-strength screw bolts; and the two supporters are connected with lug plates of the hinging posts through high-strength screw bolts to form an X-shaped crossed supporter. After the assembled steel structure self-restoration module is used, the structure can restore through the prestress steel stranded wires after great earthquake; only the supporters need to be replaced; and the operation is simpler and more convenient, so that the goals that the structure can restore to the original position without residual deformation after plastic deformation due to the earthquake, the maintenance time is shortened, the maintenance cost is reduced, and the structure can come into use as soon as possible are achieved.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic engineering and relates to a support-based energy-dissipating structure. Background technique [0002] The current anti-seismic thinking in my country is "not damaged by small earthquakes, repairable by moderate earthquakes, and not collapsed by major earthquakes". After an earthquake, the structure is allowed to have major damage, but it cannot collapse and cause casualties. However, even if the structure did not collapse after the earthquake, some important components have undergone large residual deformation and cannot be restored to their original positions, making it difficult to repair and strengthen the structure or even be demolished and rebuilt. [0003] In order to achieve the goal that the structure can return to its original position without residual deformation after the earthquake develops plasticity, so as to shorten the maintenance time, reduce the maintenance cost and put it ...
