Identifying of Passing Vehicle Load Based on Information Obtained from Monitoring of Bridge Operation State
2006
Based on the strain history information obtained from monitoring of bridge operation state,and through detailed analysis of influential line shapes of measurement points on the bridge,a BWIM(Bridge Weight in Motion) method,the single-acme acutance method that can identify passing vehicle load,is established.The still further analysis in connection with several actual examples reveals that the method can fairly accurately identify the numbers,sizes and action positions of the passing vehicles on the bridge in the state of sparse traffic volume,and can derive load under multiple vehicle action within the influential lines.
