防屈曲支撑在钢框架住宅结构中的布置研究
摘要
防屈曲支撑因其高效的抗震耗能的特点,在结构抗震设计中逐渐被推广使用。在对钢框架住宅结构抗震性能的研究中,增加防屈曲支撑的结构层间位移角明显降低,结构整体的抗震性能得到了明显的改善。通过分析防屈曲支撑的位置布置,得出一些结合住宅结构使用功能的布置原则。
Anti-buckling braces are gradually popularized and used in seismic design of structures because of their high efficiency of seismic energy dissipation. In the study of seismic performance of steel frame residential structure, the interstory displacement angle of the structure with anti-buckling braces is obviously reduced, and the overall seismic performance of the structure has been significantly improved. By analyzing the position arrangement of anti-buckling brace, some layout principles combined with the use function of residential structure are obtained.
