| 摘 要： | 针对钢框架和中心支撑钢框架两类结构,利用非线性静力分析程序计算得到结构在弹性状态和弹塑性状态下的侧移刚度.输入地震波,调整加速度峰值,对结构分别进行弹性和弹塑性时程分析,讨论两类结构在地震作用下的结构响应和能量分布的异同.结果表明,中心支撑钢框架的受力性能优于钢框架.

| Abstract: | The steel frame and concentrically braced steel frame were discussed in this paper.The lateral stiffness in elastic state and elastic-plastic state was computed by non-linear static analysis program.Using three earthquake waves,with the variation of PGA,elastic time-history and elastic-plastic time-history analysis program were used to calculate the structures response and energy distribution in earthquake.It is indicated that the mechanical behavior of concentrically braced steel frame is better than that of steel frame. |
