Abstract

The invention relates to a horizontal seamed energy dissipation prestressed shear wall structure, belonging to the technical fields of shock resistance and shock absorption in structure engineering. The shear wall structure comprises a reinforced concrete wall, an energy dissipation device, connecting steel plates, horizontal seams, prestressed reforcing steel, high-strength bolts, anchoring accessories and a foundation. The horizontal seams are arranged in the shear wall structure, and a connecting member or device is used for enhancing the energy dissipation capacity; and simultaneously, vertical high-strength prestressed reforcing steel are arranged in the shear wall to strengthen the connection performance of the structure and improve the rigidity of the structure. Thus, the horizontal seamed energy dissipation prestressed shear wall structure is suitable for industrial and civil buildings in the region where the seismic fortification intensity is higher than 6. The invention has the advantages of simple sturcture, low cost of required materials, good hysteretic energy dissipation capacity, good self-resetting characteristic, small residual structural deformation and no damage.

Description

technical field

[0001] The invention relates to a horizontally slotted energy-dissipating prestressed shear wall structure, which belongs to the technical field of anti-seismic and shock-absorbing structural engineering. Background technique

[0002] At present, building structures generally need to consume seismic energy through nonlinear deformation and damage under seismic loads. For example, in the seismic design of structures, plastic hinges are formed at the ends of beams through the principle of strong columns and weak beams. Generally speaking, even if the structure does not collapse, such nonlinear plastic deformation and damage make the structure difficult to repair or the reinforcement cost is expensive or torn down and rebuilt; on the other hand, in order to improve the seismic performance of the structure, the structure needs to have better energy dissipation Ability, which is mainly obtained through a plump hysteresis curve. However, the plump hysteresis curve...
