地震总输入能量与瞬时输入能量谱的研究
Computing the maximal grain size during incipient motion d_(cmax) and gross bed-load transport rate in Non-uniform sediment with a wide distribution are two important indexes for description its transport law, and it is also a core question for discussion in non-uniform sediment research.
宽级配非均匀沙最大起动粒径d_(cmax)和推移质总输沙率的推求是刻画非均匀沙推移质输移规律的两个重要指标,也是研究非均匀沙运动规律的核心课题之一。
The simplified methods for analyzing the total input energy of multiple freedom elastic-plastic systems are proposed to.
采用时程分析法综合考虑各种影响因素分析了单自由度弹性和弹塑性体系、多自由度弹性和弹塑性体系剪切型、弯曲型以及剪弯型结构在罕遇地震作用下的总输入能量反应及其受各类因素影响的规律,得出了上述结构的总输入能量谱曲线,提出了多自由度体系及弹塑性能量分析简化分析方法的建议,为寻求基于能量准则的结构抗震设计方法和完善结构抗震双重破坏准则提供了一定的依据。
