摘要
首先回顾了历史上数次较典型地震造成的结构震陷震害,说明了震陷研究的必要性。讨论了结构震陷研究的发展历史及其现状,揭示了其研究的发展方向。在此基础上,对结构震陷发生的内在机理及其研究方法进行了综合归纳,比较了各自的应用特点及使用范围。最后,就现行抗震规范对结构震陷计算的要求及与现实设计工作的差距进行了说明,指出了现阶段开展结构震陷研究的必要性和紧迫性。
Several typical damage examples of structural settlement made by earthquake are discussed and then the necessity of study for the earthquake-induced settlement is emphasized.Then the analysis of development on earthquake-induced settlement on the base of soil-structure interaction consideration is induced.On the basis of above introduction,the inner character and the analysis methods of earthquake-induced settlement are explained.At last,the shortage about the study on earthquakeinduced settlement between the code demanding and the working of structural design is explained.All of these show the great demand for the study on the earthquake-induced settlement.
