摘要
以一座提篮式系杆拱桥为工程背景研究索力调整中影响矩阵在桥梁专业软件中的实现方法。采用桥梁专用有限元软件MIDAS/CIVIL建立全桥空间模型。模型中索单元用桁架单元模拟,详细列出了索力调整中影响矩阵求解过程。该方法快捷、方便,并且满足精度要求,对实际工程中的索力调整具有现实指导意义。
A basket handle tied arch bridge engineering background research for the adjustment of cable tension in the bridge matrix of professional software implementation.Bridge-specific finite element software using MIDAS / CIVIL establishment of full-bridge space model,the model with the truss element simulation of cable elements,details the impact of cable tension adjustment in the matrix solution process.The method is fast,convenient and satisfy the precision requirement of practical engineering to adjust cable tension has practical significance.
