黏滞阻尼墙是一种性能良好的消能减震部件。在既有结构改造加固设计中使用黏滞阻尼墙具有节约建筑加固材料,降低施工成本,缩短工期等优点。上海某四层纯框架结构在进行整体使用功能改变设计时,结构的抗震能力不足,层间位移角超限。本文采用黏滞阻尼墙加固减震方案解决这一问题,并能节约造价,缩短工期。文章分析了变化的附加阻尼比对结构抗震性能的影响,通过对该工程项目进行改造减震设计,对比分析了无控结构和有控结构时程分析结果,可有效地解决该结构抗震能力不足的问题。本文阐述的应用分析方法以期为同类工程提供参考。
Viscous damping wall is a kind of good performance of energy dissipation components. The use of viscous damping wall in the existing structural reinforcement design has the advantages of saving building reinforcement materials, reducing construction costs and shortening the construction period. Shanghai, a four-story pure frame structure in the overall use of function to change the design, the structure of the seismic capacity is not enough, the layer displacement angle overrun. In this paper, viscous damping wall reinforcement damping solution to solve this problem, and can save costs and shorten the construction period. In this paper, the influence of variable additional damping ratio on the seismic performance of the structure is analyzed. Through the design of the seismic retrofit of the project, the time-history analysis results of the uncontrolled structure and the controlled structure are compared and analyzed, which can effectively solve the problem of insufficient seismic capacity The problem. This article describes the application of analytical methods to provide reference for similar projects.
