摘要
针对简支梁桥结构受力特点,结合荷载横向分布系数计算桥梁结构内力的基本原理,基于MIDAS/Civil软件,提出了荷载横向分布系数自动计算的有限元模型。这种新方法具有明确的计算理论,模型前、后的可视化处理使得计算过程大大地简化,并且计算结果可靠,易于桥梁工程师们掌握应用。
Aiming at the stress characteristics of simple-supported beam bridge structure,combined with the basic principle of computing bridge structure inner force of load transverse distribution coefficient and based on MIDAS/Civil software,the finite element model of automatically computing the load transverse distribution coefficient is proposed.This new method has the specific calculation theory.The visualization processing before and after the model can make the computation process is greatly simplified,and the computation result is reliable and is easy to master for application by the engineers.
