网状吊杆系杆拱桥主拱吊点隔板应力扩散趋势分析

Analysis on Stress Dispersion Trend of Suspension Point Clapboard for Main Arch of Reticulated Suspender Bowstring Arch Bridge

摘要:

对网状吊杆系杆拱桥的吊耳板及吊点隔板应力进行有限元分析计算，了解吊点处局部应力的扩散趋势，分析局部应力传递规律；同时验算结构的安全可靠性。

Abstract:

The finite element analysis and calculation are carried out on the lifting lug plate and the suspension point clapboard of a reticulated suspender bowstring arch bridge. The dispersion trend of the local stress at the lifting point is understood. The local stress transfer law is analyzed. At the same time, the safety and reliability of the structure are checked and calculated.
