Application of Fuzzy Comprehensive Evaluation Method in Long-Span Arch Bridge Damaged in Wartime

摘要

In order to quickly assess the damaged long-span arch bridge in wartime, fuzzy comprehensive evaluation method (FCEM) is applied. Considering the main factors of strength, stiffness and stability, ignoring durability and applicability, the damage performance evaluation elements of long-span arch bridge subjected to blast loading are concluded. Combined with the specific long-span arch bridge subjected to blast loading, the damage condition is assessed with FCEM. For illustration, a highway arch bridge damaged in wartime is utilized to show the feasibility of FCEM. Because of the damaged features of uncertainty and fuzzy, FCEM can effectively assess the damaged conditions of a long-span arch bridge.
