Description

A prefabricated assembled box-type high damping self-shock absorbing wall

technical field

The utility model relates to the technical field of building anti-seismic technology, in particular to a prefabricated assembled box-type high-damping self-shock-absorbing wall.

Background technique

In the actual frame structure design, the assembled infill wall is usually treated as a non-structural component. The additional stiffness of the assembled infill wall to the main structure is not considered, and only a certain reduction is made for the structural period. In practical applications, a large number of tests have shown that the presence of assembled infill walls significantly increases the bearing capacity and stiffness of the frame structure. When the frame structure is subjected to earthquake action, the assembled infill wall and the frame structure are a common stress system. Therefore, the design of the frame structure should consider the influence of the assembled infill wall on the overall seismic performance of the structure, reduce the additional stiffness of the assembled infill wall to the frame structure and prevent the damage or even collapse of the assembled infill wall.

With the growth of the prefabricated building market, the research and application of the seismic performance of prefabricated frame structures has received widespread attention, but the adverse effects of prefabricated infill walls on the structure and the hazards of earthquake damage are still lacking. In particular, compared with the concrete frame, there is a greater horizontal allowable deformation, which leads to the shear failure of the assembled infill wall, so the damage of the assembled infill wall under the action of earthquake is particularly prominent. In this regard, the academic community has proposed to use shock-absorbing walls instead of traditional assembled infill walls in the frame structure to reduce the additional stiffness of the wall to the frame structure, and provide a certain amount of additional damping to dissipate seismic energy and reduce the seismic response of the structure.

At present, the shock-absorbing wall panels have the following problems that need to be solved urgently while ensuring the shock-absorbing mechanism of the structure: First, the prefabricated wall panels are generally made on-site with low-strength concrete or mortar, and the structure of the shock-absorbing layer is complex, and the construction workload is large. The seismic wall panels also need to be able to reduce the additional stiffness of the assembled infill wall to the frame structure, and to enable the vibration-absorbing layer to play the role of frictional hysteresis energy consumption through the relative displacement of the wall panel units.
