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