摘要
采用动力时程法对K型偏心支撑钢框架在不同地震水准下的层剪力分布进行了研究。分析了强震下结构的层剪力分布规律;提出了适用于性态抗震设计的K型偏心支撑钢框架层剪力分布模式,给出了公式的拟合度。
The story shear distribution in K-brace eccentrically braced frames under different earthquake levels are investigated through nonlinear time-history analyses. The regularities of the story shear distribution in K- brace EBF under the strong ground are investigated. The distribution patterns of for performance-based seismic design are derived, and the goodness-of-fit of the this paper. the story shear in K-brace EBF distribution patterns is given in
