HEALTH MONITORING AND EVALUATION SYSTEM FOR CABLE-STAYED BRIDGE USING COMPUTATIONAL SIMULATION AND SENSOR DATA

Because of recent disasters of bridges collapses in the world, preventive maintenance and structural safety of bridges especially for larger-scale bridges have become hot research direction in civil engineer. Strong attention has been paid to health-monitoring systems which can supply bridge manager with objective data for long-term damage prediction, safety evaluation and effective decision making for optimization of repair and rehabilitation. The paper presents and details the whole health monitoring of the Poyan Lake Bridge, and the system combines three models: real-time measure model; Power Data Transfers Model; and Analysis Model. Finally the strategy for the health monitoring evaluation is proposed.
