Monitoring of a long span suspension bridge by ambient vibraton measurement

摘要

Feasibility of health nonitoring of a long span suspension brideg by ambient vibration measurement is studied. At the first half of paper, measurment installation is presented and identification scheme is constructed. Then the developed method is applied to analyze continuously monitored ambient vibration measurement at a 720 [m] span suspension bridge. The results indicates that ambient vibration measurement can provide reliable information on dynamic properties of the structure with shows the potential to be applied to health monitoring.
