Frame-core energy-dissipating and shock-absorbing structural system with multi-pendulum tuning cores

Abstract

The invention discloses a frame-core tube energy-dissipating and shock-absorbing structural system with multi-pendulum tuning core tubes, including: core tubes, multi-pendulum tuning core tubes, frame beams, frame columns, combined friction pendulum sliding hinge supports, and prestressed steel Stranded wires, controllable hinge frame beams and partial toggle energy dissipation devices. On the basis of the traditional frame-core tube structure, a core tube is changed to a combined form of a core tube and several multi-pendulum tuning core tubes. The body of the multi-pendulum tuning core tube is divided into several sections, and the base of the core tube is fixed , while the base of the multi-pendulum tuning core is hinged between each section; the multi-pendulum tuning core adds another line of defense to the traditional frame-core tube structure, making it a triple lateral force resistant system with multi-pendulum tuning The core tube frame-core tube energy-dissipating and shock-absorbing structural system can effectively improve the investment-benefit ratio of the building structure. Through its displacement amplification ability, the deformation of the damper is increased, and the shock absorption 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
