Visual Safety Evaluation of Bridges Based on the Straight Lines Failure Envelope Theory

Abstract:

The paper deduced visual safety evaluation models in each layer under the action of internal forces for the pole bracing system of bridge structure ,based on failure envelope theory. It calculated and analyzed the actual Xugou especially big bridge project with these evaluation methods. Analyzed visibility graph of bridge structure, tried to find out directly concrete distribution and the safety degree of structure on visible group points in intra-regional each point to corresponding coordinateof octahedral failure envelope. It can finally realize quantitative and visual safety assessment for bridge structure, and can provide necessary reference to scientific management and planning optimal maintenance scheme of bridge engineering.
