Description
Technical Field
The invention belongs to the field of structural vibration control of building engineering technology, and particularly relates to a self-adaptive friction energy dissipation cantilever system for resisting multiple catastrophes of a super high-rise building structure.
Background
The core tube-cantilever-giant column structure system is a structure form widely applied to domestic and international super high-rise buildings at present. The core tube in the middle of the structure is connected with the giant columns arranged on the periphery through the outrigger truss to form a lateral force resisting system (marked as a traditional outrigger system) of the structure together, so that the lateral rigidity of the structure can be obviously improved, and the deformation of the structure under wind load (particularly under the action of average wind) can be effectively limited. However, the traditional cantilever system only provides rigidity, and is lack of energy dissipation means, so that the control effect on the structure under dynamic catastrophe effects such as earthquake, pulsating wind and the like is limited. Therefore, the energy dissipation cantilever system is produced at the same time. The energy dissipation outrigger system is based on the deformation characteristic of the system, a damper is arranged at the connecting part of the giant column and the end part of the outrigger truss, and the damper is fully exerted to provide extra energy dissipation capacity for the structure system by utilizing larger vertical deformation concentrated between the giant column and the outrigger truss.
On one hand, the energy dissipation boom breaks through the rigid connection between a giant column and a boom truss in the traditional boom, replaces a damper, and loses the static rigidity of the structure to a certain extent, so that the effect of controlling the static deformation of the structure under the action of average wind is reduced; on the other hand, the super high-rise building structure inevitably encounters risks of earthquakes (small earthquakes, medium earthquakes and large earthquakes) of different levels in the service period, and the energy dissipation extension arm designed for a certain level earthquake cannot adjust the energy dissipation capacity in a self-adaptive manner, so that the super high-rise building structure is often difficult to effectively exert the effect when resisting other levels earthquakes. Therefore, in current engineering practice of super high-rise building structures, an effective measure which can give consideration to both static deformation and dynamic response of the structures and can provide self-adaptive energy consumption according to catastrophe levels is urgently needed.
Aiming at the problems, the invention provides a self-adaptive friction energy dissipation cantilever system for resisting multiple catastrophes of a super high-rise building structure by combining the characteristics of an energy dissipation cantilever system; the invention can realize the effective resistance of the super high-rise building structure to multiple disasters such as average wind, pulsating wind, small earthquake, medium earthquake, large earthquake and the like by introducing the self-adaptive friction energy dissipation device between the end part of the outrigger truss and the peripheral giant column, and is particularly shown in the following steps: aiming at the action of average wind, the end part of the boom and the giant column in the proposed self-adaptive friction energy dissipation boom system do not slide, and the system is equivalent to a rigidly connected traditional boom, and provides additional static rigidity for the whole structure to reduce static deformation caused by the average wind; when the self-adaptive friction energy dissipation boom system encounters pulsating wind action or small shock, slight sliding is generated between the boom end part and the giant column in the self-adaptive friction energy dissipation boom system, and smaller friction energy consumption is provided to consume the energy input to the whole structure by the pulsating wind and the small shock; when encountering medium earthquakes, the self-adaptive friction energy dissipation cantilever system can provide larger friction energy dissipation and consume the energy of the medium earthquakes; when a large earthquake occurs, the provided self-adaptive friction energy dissipation boom system can provide larger friction energy dissipation to meet the energy dissipation requirement of the large earthquake, thereby achieving the purpose of resisting multiple disasters.
