Method of Damage Evaluation of Long-Span Arch Bridge Subjected to Blast Loading

Article Preview

Abstract:

A variety of conventional weapons equipped with explosive are used to destroy the significant long-span arch bridge. Because of the special function of the weapons and the complexity of the arch bridge, the damage results with the features of uncertainty and fuzzy are assessed with fuzzy theory. Combined with the standards for technical condition evaluation of highway bridges and wartime specific requirements, the fuzzy mathematical model based on the fuzzy mathematics theory and method is established to judgment comprehensively the arch technical condition. The hirarchy fuzzy comprehensive evaluation method is applied to determine the technical state grade of the damaged arch bridge. The method of damage evaluation provides the effective reference for the emergency repairmen of the arch bridges.
