Problems solved by technology

However, even if the structure did not collapse after the earthquake, some important components had a large residual deformation and could not be restored to their original positions, making it difficult to repair and reinforce the structure or even be demolished and rebuilt

Abstract

The invention discloses an assembly type steel structure self-return module based on slotting steel plate shear wall energy consumption. The module comprises vertical edge components, transverse guide components, connecting components and a slotting steel plate shear wall, wherein multiple post-tensioned prestressed steel strands are arranged along the two transverse edge components, and are anchored at the outer side wing edges of the two vertical edge components to form a prestressed frame; and the connecting components are arranged at the two ends of the slotting steel plate shear wall in the prestressed frame, and are connected with the transverse edge components through high-strength bolts. The module can simplify the construction process and improve the industrial degree; and the structure is returned to the normal position through the prestressed steel strands after major earthquake, and the slotting steel plate shear wall is not required to be replaced, so that the operation is simpler and more convenient, the structure still can be returned to the normal position without generating residual deformation after encountering the earthquake development plasticity, the maintenance time is shortened, the maintenance cost is reduced, and the module is put into the use target as soon as possible.

Description

technical field [0001] The invention belongs to the technical field of seismic engineering and relates to an energy-dissipating structure based on a slotted steel plate shear wall. Background technique [0002] In recent years, with the rapid economic development and the rapid advancement of urbanization, the development of buildings has also entered a new stage, and a number of high-rise and super high-rise buildings have sprung up. High-rise buildings conform to the national architectural design guidelines in terms of economy, applicability, and aesthetics, and also represent the economic development level of the country and region. [0003] Generally, loads acting on buildings can be divided into vertical and horizontal loads. As the height of the building increases, the horizontal load gradually plays a controlling role, so in the structural design of high-rise buildings, the selection of the lateral force-resisting system is very important. As a new type of lateral fo...
