移动荷载作用下空间索面提篮拱桥吊杆的响应分析
Response Analysis of the Boom of Space Cable-stayed Lift Arch Bridge Under Mobile Loads
摘要
Abstract
The safety of the boom of a space four-cable-surface lattice arch bridge is affected by a variety of factors,among which the influence of the moving load is particularly critical.In this study,Wenchang Bridge is taken as an engineering example,and MIDAS/Civil software is used to establish a model,adopt single-vehicle and multi-axis simplified moving load loading method,set up a variety of working conditions to simulate the vehicle crossing the bridge,and carry out a study on the response of the boom under moving load.The results show that:the change of cable force caused by the vehicle is relatively larger in the inner cable face,and the loading side is higher than the other side;the deformation of the inner boom face is distributed in M-shape,which is characterized by the small elastic deformations of the boom corresponding to the pivot point and the middle of the span and the large elastic deformations of the boom at the quarter point;the short boom has large stiffness,high self-oscillation frequency,weak buffering capacity,and the dynamic response is more sensitive to the moving load.关键词
