摘要
本文用计算分析的方法研究了结构在弹塑性地震反应过程中的阻尼耗能与塑性耗能的数量关系问题。研究结果表明,在弱非线性反应以至强非线性反应的情况下,结构的阻尼耗能均比塑性耗能多出一定数量,从不同的方面又一次说明了阻尼问题的重要性。
n this paper the quantity relation between the damping energy-dissipation and the plastic one of multistory buildings is studied by using the computational method.The structure is subjected to seismic loading and in elastic-plastic response.The results show that,no matter when the structure is in weak nonlinear response or in strong nonlinear response,the damping energy-dissipation is always greater than the plastic one,which means that,the damping is of the important influence on the elasto-plastic earthquake response of strtictures.
