摘要
通过以结构构件设计为主,消能器为强度补充的设计思想减少以往基于位移设计方法中大量的迭代过程。在现阶段我国没有合适的位移设计反应谱情况下,建议采用规范中加速度转化为绝对位移的方法来建立位移反应谱。两个数值算例分别采用具体地震记录建立的位移反应谱及加速度转化的绝对位移反应谱来设计,通过加速度时程分析分别验证了该设计方法的准确性与实用性。
Iterative process is shortened through the idea that the design procedure focuses on the structural component, and dissipation energy system makes up the insufficiency of the intensity. The design procedure is close to the China Code. Displacement response spectrum is established by the method, which translates the acceleration response spectrum from the China Code to the absolute-displacement response spectrum. The results of numerical examples show that the design procedure is feasible and satisfies the precision requirement of civil engineering.
