【摘要】 根据有限条法原理,把渡槽槽身划分为若干有限条,推导出渡槽槽身结构的单元刚度矩阵、质量矩阵的显示表达式。采用空间梁单元模拟渡槽支架,联接槽身和支架的支座采用弹性元件单元模拟;采用附加质量法考虑水体的动水作用;计算了大型渡槽结构在三种工况分别输入三种地震波作用下的时程响应。更多还原

【Abstract】 Based on the theory of finite strip method,the aqueduct body is discretely meshed into some strips,and the explicit formulas for the element stiffness and mass matrix of the aqueduct body are derived.The braces of the aqueduct are simulated by using beam elements,and the rubber supports linking the aqueduct body and its braces are simulated by using spring elements.Then,the earthquake time history response of the large-scale aqueduct with fluid influence by added mass method is discussed under three cases and during respectively inputting three synchronous earthquake waves.更多还原
