金属消能器在框排架结构改造中的应用

Application of metal energy dissipation device in reconstruction of frame bent structure

为促进金属阻尼器在既有建筑改造工程中的应用,总结减震设计思路及方法。该方法避免了已有减震设计理论中假定过多、过程复杂、不便应用的问题。利用此方法,采用墙式连接金属消能器对某框排架改造工程进行减震设计,介绍设计过程及技术难点。提出的金属消能器减震设计方法、排架铰接梁柱节点加固做法及性能化加固设计思路可供类似工程参考。

In order to promote the application of metal energy dissipation device in the reconstruction of existing buildings, a design method of energy dissipation is proposed. This method avoids the problems of too many assumptions,complex process and inconvenient application in the existing design method of energy dissipation. A frame bent structure is selected and metal energy dissipation devices with wall-connected are used to improve the seismic performance of the structure based on the proposed design method of energy dissipation, and the design process and technical difficulties are introduced. The design method with metal energy dissipation device, reinforcement method of beam-column hinged joints and performance-based reinforcement design proposed in this paper can be used as reference for similar reconstruction projects.
