Vibration damping wall with self-resetting function and internally containing bidirectional damping particles

Abstract

The invention discloses a vibration damping wall with a self-resetting function and internally containing bidirectional damping particles. In the normal use state, the vibration damping wall with theself-resetting function and internally containing the bidirectional damping particles can meet structure requirements for bearing capacity, lateral stiffness and intensity and the like, has good vibration damping performance when blasting or a hurricane or an earthquake occurs, can reduce the damage degree of a building main body structure, and has the self-resetting function after vibration. Thevibration damping wall with the self-resetting function and internally containing the bidirectional damping particles comprises energy dissipation building blocks, hole channels, the damping particles, soft hole plugs, springs, rebound plates, buffer plates, steel plates, high-strength springs, prepressing rods, bonded rebars, mortar, sound-insulating plates, frame beams and frame columns. The energy dissipation building blocks can realize bidirectional vibration damping of the vibration damping wall to a frame structure main body, the vibration damping efficiency is improved, and the flexibleconnection between the vibration damping wall and the frame columns can prevent the occurrence of short columns existing in the frame columns and prevent the frame columns from being subjected to shear failure; and self-resetting connecting devices which connect the wall and the frame columns can provide the lateral stiffness for the frame structure, and meanwhile, the wall can further be enabledto have the self-resetting function after the vibration.

Description

technical field [0001] The invention relates to a vibration-damping wall with strong energy dissipation capacity in buildings, self-resetting function and built-in two-way damping particles, which meets structural requirements such as bearing capacity and lateral stiffness in normal use, and Installation is quick and easy. It has sufficient ductility and energy dissipation performance in explosions, hurricanes and earthquakes, reduces damage to buildings, and has the function of self-resetting walls after earthquakes, and belongs to the technical field of vibration reduction control in structural engineering. Background technique [0002] With the development of society and the frequent occurrence of earthquakes in recent years, people pay more and more attention to the anti-seismic performance of buildings, but the anti-seismic design of buildings in most parts of our country is not perfect. Previous earthquake disasters have shown that due to improper construction, design...

Problems solved by technology

Reinforced concrete shear walls have a large reinforcement ratio, complex construction, high engineering costs, and less applications than reinforced concrete frame structures

Generally, the combined wall only improves the anti-seismic performance through the combination of different walls, and the anti-seismic effect is not significant.

In recent years, some researchers have proposed wall forms with vertical deformation joints, but for thicker walls, the process of opening joints is complicated, the sound insulation effect is poor, and the design is difficult, and deformation joints are easy to appear in earthquakes. Partial damage and not easy to repair
