A self-resetting lateral shear-resistant wall-to-floor connection device and its application method

Abstract

The invention discloses a connection device between a self-resetting anti-lateral shear wall and a floor slab and a use method thereof, which comprises a self-resetting anti-lateral shear wall, a floor, a friction device and a carbon fiber reinforced laminated low-damping rubber bearing. The side shear wall is connected with the floor slab through the carbon fiber reinforced laminated low damping rubber bearing. Beneficial effects: It can reduce the acceleration of the floor and maintain the stability of the floor. The energy consumption section in the middle of the friction device consumes seismic energy. The carbon fiber reinforced laminated low-damping rubber bearing is fixed at the gap between the two sides of the self-resetting lateral shear wall and the floor. , this bearing has an almost linear elastic response under large shear deformations with significant compressive stiffness for maintaining the out-of-plane stability of self-resetting lateral shear walls and providing predictable and reliable postelastic stiffness for deformed connections , the carbon fiber reinforced rubber layer is used to prevent the collision damage between the self-resetting anti-lateral shear wall and the floor.

Description

technical field [0001] The invention relates to the technical field of deformable connection between a floor slab and a shear wall, in particular to a connection device and configuration method for a self-resetting lateral shear wall and a floor slab. Background technique [0002] Due to the development of social economy, in the design of buildings and structures, the safety of structures and the function and damage of structures after encountering earthquake loads and impact loads have been paid more and more attention. In previous studies, it was found that adding shear walls can better improve the seismic effect. Shear walls are usually constructed of reinforced concrete with strong rigidity and resistance to stress damage, while self-resetting lateral shear walls not only have high rigidity, high bearing capacity, and flexible layout, but also can achieve greater The elastic lateral movement reduces the damage and residual strain of the wall. [0003] However, at prese...

Problems solved by technology

[0003] However, at present, most of the existing self-resetting anti-lateral shear walls and the connecting devices of the floor are mostly complicated in structure and connection, and when the device is vibrated, the device cannot reduce the acceleration of the floor, thereby reducing the stability of the floor, and The seismic energy during an earthquake cannot be effectively consumed, and the research on building structures at home and abroad has seldom considered the influence of floors on the mechanical properties of nodes or structures. How to transfer the inertial force of floors without affecting the self-resetting performance of nodes or structures For the shear wall structure, the connection construction measures between the floor slab and the shear wall are very important
