Abstract

The invention relates to the technical field of structural seismic resistance and energy dissipation and seismic mitigation, and particularly relates to a damping and energy-consuming type outrigger truss high-rise structure system. The damping and energy-consuming type outrigger truss high-rise structure system comprises a core tube arranged in the middle of a building, a frame column arranged on the periphery of the building and an outrigger truss arranged between the core tube and the frame column; the outrigger truss comprises an upper chord rod connected with the core tube and the frame column, a lower chord rod arranged below the upper chord rod in parallel and connected with the core tube and the frame column, and a diagonal web rod arranged between the upper chord rod and the lower chord rod; and a damper is vertically arranged on the frame column, one end of the diagonal web rod is connected to the damper, and the other end of the diagonal web rod is connected to the core tube. The reinforcing effect of reducing structure sidesway of a common outrigger truss can be achieved, the overturning moment of the core tube is reduced, and the situation that due to the fact that the outrigger truss is arranged, a relatively weak layer is formed, and consequently floor rigidity and bearing capacity are suddenly changed can be avoided.

Description

technical field [0001] The invention relates to the technical field of structure anti-seismic and energy dissipation and shock absorption, in particular to a high-rise structure system of a shock-absorbing and energy-dissipating outrigger truss. Background technique [0002] At present, earthquake action and wind load action are the two most prominent factors in the design of super high-rise buildings. Under the action of earthquake and wind force, structural deformation and wind-resistant comfort should not exceed the limit specified in the code, which is the focus and difficulty of high-rise design. Most super high-rise structures use the outer frame column and the middle core tube structure system. Outrigger trusses are arranged at a certain floor height between the outer frame column and the inner core tube. When the structure is subjected to horizontal loads, the core is adjusted through the coordination of the outrigger truss One side of the peripheral frame column is...
