Research on Instantaneous Energy of Bilinear System
【摘要】 研究了不同周期弹性及双线性系统在地震作用下最大瞬时输入能量对应的位移与结构最大位移之间的关系 ,分析了双线性系统参数对该关系的影响 .讨论了弹性及双线性系统的等价速度谱及其变化规律 .并对如何由瞬时输入能量评价结构的最大位移进行了初步探讨 .
【Abstract】 In this paper,the relation between instantaneous energy of earthquake actions and maximum displacement of the structure for both the elastic and bilinear SDF systems of different period was studied.The study also took the influence that the system parameter acted on the relation into account.And the equivalent input velocity and its changing rule were discussed in the article.The way to estimate the maximum displacement from the instantaneous energy was also discussed.
