论地震地面运动中的持续时间

对地震动持时的宏观影响、影响地震动持时的因素、持时对工程结构的影响进行了阐述,并分析了考虑地震动持时的抗震设计,通过分析,认为对地震动持时的研究可以从持时与其他两个要素的耦合方面去突破,此外结合结构的非线性反应的集中现象,提出了关于间隔薄弱层的抗震设计的设想。

Discussion on the duration of ground motion in earthquake

This thesis expounds macro impacts of duration of ground motion in earthquake,factors influencing the duration of ground motion in earthquake,and impacts of duration on engineering structure,and analyzes anti-earthquake design of duration of ground motion in earthquake.Through analysis,it finds out that the research of duration of ground motion in earthquake can be started from duration and other tow contingencies.In addition,combining with central phenomenon of nonlinear reflection of the structure,it proposes anti-earthquake design concept of interval weak layer.
