Static Analysis of Large-scale Multi-troughs Rectangular Aqueduct Structure
摘要
Abstract
According to the structure of large-scale multi-troughs rectangular aqueduct and its mechanical characteristics ,the structural mechanics method was applied to decompose the complicated space structure into two connected plane problems .In the lateral calculation ,the beam bottom was supported by the longitudinal beams .According to the displacement coordination theory ,the elastic supporting force calculation formula of double and triple troughs were proposed ,and the lateral force and the elastic support force of the structure can be obtained .The elastic supporting forces were regarded as loads and acted reversely on the longitudinal beams ,and then the forces on the longitudinal beams were calculated .The solid 3D finite element software (MIDAS) was adopted to simulate the triple-troughs rectangular aqueduct ,and the results obtained from the finite element model and the structural mechanics method were compared ,which verified the reliability of the proposed method and accuracy of the formula .Consequently ,the method used to calculate the aqueduct structure can meet the accuracy requirements of engineer-ing desig n .关键词
