Vertical viscous damper connected energy-dissipating-and-shock-absorbing outrigger truss high-rise structural system

Abstract

The invention relates to a vertical viscous damper connected energy-dissipating-and-shock-absorbing outrigger truss high-rise structural system. According to the structural system, by taking a framework-core tube structure for example, an outrigger truss is arranged between a core tube and giant concrete columns, so as to coordinate the deformation between the core tube and a framework under the action of a horizontal load; the outrigger truss consists of horizontal chord members, diagonal web members and vertical web members; corbels are arranged on peripheral giant columns, joints between the outrigger truss and the giant columns are appropriately disconnected, and viscous dampers are arranged vertically; the viscous dampers are fixedly arranged on the corbels, one position of the outrigger truss is connected to the dampers, and one position of the outrigger truss is hinged to the giant columns; under the action of wind vibration and/or earth shock, the giant columns and the outrigger truss undergo relative dislocation, and viscous fluid in the viscous dampers passes through a damping passage under the action of pressure difference, so that a damping force is generated, and the vibrational energy of an outside input structure is dissipated. The structural system has the advantages that the viscous dampers can generate an energy dissipating effect by using the relative dislocation between the giant columns and the outrigger truss, and the structural system is effective under the action of wind vibration and/or earth shock, so that the earthquake resistance of a main body structure can be excellently improved.

Description

technical field [0001] The invention relates to a high-rise structure system of an energy-dissipating shock-absorbing outrigger truss connected by a vertical viscous damper, and belongs to the technical field of anti-seismic and energy-dissipating shock-absorbing engineering structures. Background technique [0002] Earthquake load and wind load are the two most prominent factors in the design of super high-rise buildings. Satisfying the wind resistance comfort and reducing the dynamic response of the structure under the action of an earthquake so that it does not exceed the specified limit are the core of high-rise design, and the design and installation of the damper is particularly important. Most super high-rise structures adopt the structure system of peripheral giant columns and core tubes, and the core tube and peripheral giant columns are connected by outrigger trusses. When the structure is subjected to horizontal loads, the outrigger truss coordinates the force an...

Problems solved by technology

The outrigger truss plays a huge role in resisting horizontal loads, but this position produces a sudden change in stiffness and forms a weak layer, which is not conducive to the earthquake resistance of the structure
