摘要
Abstract
Based on the self-developed vehicle bridge coupling vibration analysis program and the improved adaptive ge-netic algorithm,a bridge structure damage identification method using vehicle induced vibration response was developed.First,the possible damage mode of the structure was assumed,and then the vehicle induced vibra-tion response of the bridge under a certain damage mode was calculated by using the vehicle bridge coupling analysis program,and the calculated value was compared with the vibration response value under the real damage condition efficiently,so as to realize rapid damage identification.By setting a variety of different work-ing conditions,the impact of various factors on the efficiency of bridge damage identification was analyzed,and the effectiveness of the method was verified.关键词
