Design and Implement of the Urban Bridge Cluster Monitoring Online Assessment System

Abstract:

Bridge health monitoring system (BHMS) is a package of technologies for structural monitoring, control, maintenance and management. Making use of the fusion of technologies from different disciplines, such as sensing, communication, signal processing, system identification, etc., the system is empowered to simultaneously get all kinds of information which reflect the safety conditions of bridge structure, and provide scientific proof for the analysis of bridge health. The assessment method is the core of the BHMS. In the conventional assessment procedure, there is significant influence of subjective factors involved. A feasibility study on the use of fuzzy comprehensive evaluation method in the bridge condition assessment is presented in this paper. The applications of fuzzy mathematics in condition assessment of bridges were discussed. Based on the research of present methods, analytical hierarchy process and fuzzy mathematics were integrated and applied in condition assessment of the project of main roads bridge Online Safety Monitoring Management System in Hangzhou (Phase II), a web-based urban bridge cluster monitoring system have been established. From a continuous beam bridge case study, it is observed that the fuzzy comprehensive evaluation method is capable of simulating the bridge condition evaluation process and has a good application.
