Abstract :
According to the characteristics of long-span continuous rigid frame bridges, this paper constructs a bridge intelligent control and safety warning system. By analyses on the mechanical properties of the continuous rigid frame bridges in operation, choosing the key control sections and parameters, it can get dynamic monitoring data from reliable data acquisition systems and data transmission system, and analyzes a state of the structural health by damage assessment, capacity assessment and degradation assessment. Based on the assessment results, connecting with the limit module and self-checking module, it can also make early warning of structural safety and put forward a feasible maintenance scheme after comparison and selection. The results contribute to improvement of the bridge health monitoring system.
