摘要
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。
The viscous damping wall is an energy dissipation component with high performance. In the strengthening design of existing structures with viscous damping walls, it can save building materials, reduce the construction cost, shorten the construction period, etc. When a frame structure is put to design to change its whole function in Shanghai, its seismic capacity is insufficient, and interlayer displacement angle overrun. This paper introduces the viscous damping wall strengthening design scheme to solve this problem, and the scheme can save cost, shorten the construction period. This paper analyzes the effect on the structural seismic perform- ance with various additional damping ratios, and comparative analyzes the time history analysis results about no control structure and control structure. The application of the analysis method provides a reference for similar projects.
