特大型梁式渡槽底板的动力结构性态计算及研究
Calculation and Research on Dynamic Structural State of the Bottom Plate of Extra-large Beam Aqueduct
摘要
Abstract
Since the seismic safety of extra-large beam aqueduct bottom plate is the key to the normal service of the aqueduct,it is necessary to deeply study its structural seismic characteristics.In order to study the dynamic characteristics of the aqueduct and its floor,the seismic response of key parts of the extra-large aqueduct body is studied by time-history analysis method,the maximum value of the seismic response of the aqueduct body is calculated and the dynamic characteristics of the floor of the aqueduct body are analyzed.Further,the structural dynamic response and dynamic characteristics of aqueduct bottom plate are calculated and studied.It can be seen from the engineering case that the result of the finite element calculation and simulation method accords with the dynamic characteristic law of extra-large aqueduct,and the method has high engineering reliability.The research results can be used for seismic calculation and optimal design of slab of large beam aqueduct.关键词
