【摘要】 以大跨度简支梁式渡槽为对象,研究了流固耦合对其纵向地震响应的影响。试验表明流固耦合对渡槽纵向位移地震响应影响明显,说明纵向流固耦合作用不可忽视。其次,在渡槽有水的情况下,采用附加水质量方法的计算结果会有比较大的误差,应该充分考虑到流固耦合的影响。另外,在设计中可用无水情况作为渡槽纵向抗震的控制工况。更多还原

【Abstract】 Large-span simply supported beam aqueduct is taken as the research object,this article studies on the influence of FSI on its longitudinal seismic response.Research shows that,first,FSI has obvious effect on the longitudinal seismic response of aqueduct,the effects of FSI are nonnegligible.Second,in the case of water in aqueduct,errors of the calculated results of additional water mass method are were bigger,which should be fully taken into account the influence of FSI.In addition,waterless condition should be as control load case during design.更多还原
