Problems solved by technology

However, after the outrigger truss is installed, the stiffness of the structure along the height direction will be uneven. The core tube of the reinforced layer has obvious internal force mutations. The weak layer effect appears, which has a bad influence on the earthquake resistance of the structure

Abstract

The invention relates to an inertial type shock-absorbing layer system used in the fields of civil engineering and energy infrastructure, which comprises an upper truss and a lower truss, an anti-buckling restrained brace energy consumption unit and a friction limit type viscous inertial system. The system provides the basic rigidity of the shock-absorbing layer through the upper truss group and the lower truss group, and limits the sliding of a lead screw through the friction limit unit of the inertial system under the action of wind load and small earthquake. When the external loading actionis enhanced, by relaxing the restraint with the friction limit unit of the inertial system, the energy of the shock-absorbing layer is dissipated by utilizing the friction damping, the viscous damping and an anti-buckling restrained brace hysteresis unit. The shock-absorbing layer establishes a systematically complete energy consumption path and a two-stage rigidity adjusting mechanism. The designed anti-buckling restrained brace meets the energy consumption requirement of the multi-stage support. The friction limit type viscous inertial system improves the energy consumption efficiency of the shock-absorbing layer. The inertial type shock-absorbing layer system is convenient and flexible, can effectively absorb and dissipate earthquake energy, has the advantages of high energy consumption efficiency, strong robustness, easy repair after earthquake and the like, and has good popularization and application value.

Description

technical field [0001] The invention belongs to the field of civil structure engineering, relates to an energy-dissipating and shock-absorbing structure, in particular to an inertia-type shock-absorbing layer system. Background technique [0002] The frame-shear wall structure is a commonly used structural system in high-rise and super high-rise buildings. In order to improve the integrity between the shear wall and the mega-frame, outrigger trusses are usually set in some floors as reinforcement layers. While the outrigger truss increases the axial force of the outer frame under horizontal action, it also reduces the overturning moment borne by the shear wall. Therefore, the outrigger truss can effectively increase the lateral stiffness of the structure and reduce the lateral displacement of the structure. However, after the outrigger truss is installed, the stiffness of the structure along the height direction will be uneven, and the core tube of the reinforced layer has a...
