摘要: 随着消能减震技术发展日趋成熟,基于结构性能需求的各种消能器产品应运而生. 目前建筑市场应用较广泛的消能器主要包括位移型和速度型两种. 根据项目应用实际情况,大部分减震项目使用的消能器类型单一,未能结合不同结构体系的特点、需求及限制进行消能减震机理及效率研究,且经济性一般. 在设计日趋精细化形势下,提出基于结构性能需求的组合消能减震技术,即针对不同结构体系、不同楼层等根据性能需求“量身定制”相应类型的消能器,以最大程度发挥不同类型消能器减震效率及共同作用的一种组合减震技术. 两个不同工程实例的研究结果表明:相比传统单一消能器方案,组合消能减震技术可根据结构特点及性能需求,为不同阶段及设计水准下的结构提供附加刚度及附加阻尼,“量身定制”消能器减震机理明确且减震效率、经济性均较好.

Abstract:With the development of seismic energy dissipation technology, a variety of damper products based on theperformance requirements of the structure come into being. Energy dissipation shock absorbers widely used in theconstruction market mainly include displacement type and velocity type at present. According to the practical application,most of the dampers used in the projects are of single type, which can not be combined with the characteristics,requirements and limitations of different structural systems to further study the mechanism and efficiency of seismic energydissipation, and the economy is general. Under the situation of more and more refined design, a combined seismic energydissipation technology based on structural performance requirements were proposed, the corresponding types of energydissipation devices were ‘ tailor-made’ to maximize the efficiency of different types of energy dissipation devices and acombination of shock absorption technology according to the performance requirements for different structural systems,different floors etc. The research results of two different engineering examples show that compared with the traditional singledamper scheme, the combined seismic energy dissipation technology can provide additional stiffness and additional dampingratio for the structure at different stages and design levels according to the structural characteristics and performancerequirements, the damping mechanism of the‘ tailor-made’ damper is clear and the damping efficiency and economy aregood.
