【摘要】 基于能量概念的抗震设计方法能较好地反映地震动三要素,特别是持续时间对结构引起的累积损伤破坏的综合影响,因此日益受到地震工程研究的重视。本文对地震作用下结构的总输入能量、结构总耗能的分配与分布、结构的耗能能力和具体设计方法等方面的研究现状进行了综合分析和介绍,为能量抗震方法的应用和推广提供参考。更多还原

【Abstract】 Design method based on energy concept can better reflect the destruction caused by seismic input motion,particularly by effective duration.Therefore it is increasingly attached importance to the international seismic engineering research.In this paper,the authors analyze and introduce the design method of structures based on energy concept,including the calculations of total input energy,the distribution of hysteretic energy,the energy absorption capacity of structure and energy design method,providing references for the applications of the design method of structures based on energy concept.更多还原
