| Abstract: | Bridge monitoring is conducted at the Akashi Kaikyo Bridge which is the world's longest span suspension bridge. The purposes of the monitoring are for daily traffic control, real-time monitoring during extreme events, long-term monitoring for bridge health indices and design verification. The paper presents a couple of examples of bridge monitoring and design verification results. The results showed that short- and long-term monitoring gives possible health indices to detect structural damages. In addition, study on design verification identifying vibration characteristics such as natural frequency and structural damping showed that structural damping greatly affecting flutter stability is larger than the design value. |
