摘要
通过地震影响系数和场地设计谱在不同阻尼比情况下的比较,同时对八个钢框架在阻尼比为0．02和0．05时的用钢量和地震反应进行比较,得出结论为通过改变阻尼比达到节省钢材的目的是可行的,特别是以刚度控制的结构。
Through the comparison of earthquake influence quotiety with site design spectra under different damping ratio, eight steel framework and quake response are compared when damping ratio is 0.02 and 0.05. The conclusion is that it is feasible to save steel quantity through changing damping ratio, especialy the stiffness controlling structure.
