摘要
本文从能量的观点,利用CANNY程序对普通钢筋混凝土框架结构进行了分析。通过对3种不同框架结构在不同地震动(31条)输入下的能量反应分析,研究了滞回耗能及阻尼耗能与总输入能的关系。针对本文模型的计算结果,给出了滞回耗能与总输入能关系的表达式,并初步探讨了其影响系数。研究表明,滞回耗能及阻尼耗能与总输入能之间有良好的线性关系。
This paper analyzed ordinary RC frame structures with CANNY program in the viewpoint of energy. Through the energy response analysis of three different frame structures under input of 31 different ground motion records, the relationship of the hysteretic energy and damping energy with the total input energy was studied. The relational expression of the hysteretic energy and damping energy was given based on the model in this article, with coefficient factors in the expression preliminary studied. The study showed that the hysteretic energy and damping energy had a good linear relationship with the total input energy.
