Description

Prefabricated assembled box type high damping self-damping wall body

Technical Field

The utility model relates to the technical field of building earthquake resistance, in particular to a prefabricated assembled box type high-damping self-damping wall body.

Background

In practical frame structural designs, the fabricated infill wall is generally treated as a non-structural member, and the structural period is only somewhat reduced without regard to the additional stiffness of the fabricated infill wall to the main structure. In practical application, a large number of experiments show that the existence of the spliced infill wall obviously increases the bearing capacity and rigidity of the frame structure. When the frame structure bears the earthquake action, the spliced filling wall and the frame structure are a commonly stressed system, so that the influence of the spliced filling wall on the whole earthquake resistance of the structure is considered in the design of the frame structure, the additional rigidity of the spliced filling wall on the frame structure is reduced, and the damage and even collapse of the spliced filling wall are prevented.

With the growth of the market of the fabricated building, the research and application of the seismic performance of the fabricated frame structure are widely focused, but the adverse effect of the fabricated filling wall on the structure and the hazard of the seismic damage are still not emphasized. Compared with concrete frames, the concrete filling wall has larger horizontal allowable deformation, so that the spliced filling wall is easy to shear and damage, and the problem of damage of the spliced filling wall under the action of an earthquake is particularly remarkable. In this regard, the academy proposes that the damping wall body is adopted in the frame structure to replace the traditional spliced infill wall, so that the additional rigidity of the wall body to the frame structure is reduced, a certain additional damping can be provided for dissipating the earthquake energy, and the earthquake response of the structure is reduced.

At present, the damping wallboard has the following problems to be solved when guaranteeing that the structure exerts a damping mechanism: firstly, the assembled wallboard is generally manufactured on site by adopting concrete or mortar with lower strength grade, the shock absorption layer has complex structure and large construction workload, and when the wall body is damaged by earthquake, the wall body is difficult to replace in time due to the complex traditional connection structure, so that the normal use function of the building is difficult to recover quickly; secondly, in the process of exerting slip energy consumption, due to lack of measures for limiting out-of-plane displacement of the shock absorption wallboard, out-of-plane instability is easy to occur, the shock absorption wallboard also needs to be capable of reducing the additional rigidity of the assembled type filling wall to the frame structure, and the shock absorption layer can exert friction hysteresis energy consumption effect through relative dislocation of wallboard units.
