Frame-corewall energy dissipation and seismic mitigation structure system with multi-pendulum tuning core tubes

Abstract

The invention discloses a frame-corewall energy dissipation and seismic mitigation structure system with multi-pendulum tuning core tubes. The frame-corewall energy dissipation and seismic mitigation structure system comprises a corewall, the multi-pendulum tuning core tubes, a frame beam, a frame column, a combined friction pendulum sliding hinge support, a prestressed steel strand, a controllable hinge frame beam and a local toggle type energy dissipation device. On the basis of a traditional frame-corewall structure, the corewall is changed into a combined form of the corewall and a plurality of multi-pendulum tuning core tubes, a tube body of each multi-pendulum tuning core tube is divided into a plurality of sections, a base of the corewall is fixedly connected, and the base of each multi-pendulum tuning core tube is hinged to each section; the multi-pendulum tuning core tubes add a defensive line for a traditional frame-corewall structure, so that the traditional frame-corewall structure becomes a triple lateral force resistance system, and the frame-corewall energy dissipation and seismic mitigation structure system with the multi-pendulum tuning core tubes can effectively improve the investment-benefit ratio of a building structure. Through the displacement amplification capability, the deformation of a damper is increased, and the damping effect of the structure is improved.

Description

technical field [0001] The invention relates to a frame-core tube energy dissipation and shock absorption structural system with multi-pendulum tuning core tubes, which belongs to the field of design and shock absorption of high-rise building structures. Background technique [0002] With the rapid development of our country's economy, the urbanization process is also accelerating, and the urban building space is becoming increasingly tight. In order to meet people's needs for various civil buildings, more and more high-rise buildings appear in various large and medium-sized cities. The horizontal load effect caused by earthquake and wind load is the main design factor in the structural design of high-rise buildings, and the design of the anti-lateral force system becomes the key point of high-rise buildings. Frame-core tube structure is a common dual lateral force-resisting system in high-rise buildings. Among them, the core tube is the first line of defense, which bears m...

Problems solved by technology

[0004] At present, there are many methods for tuning and damping structures, most of which are to add a mass-tuned damper to the structure, but this device is an accessory device with a small mass and generally can only control the first-order structural period, so the vibration damping performance and The efficiency is not ideal
