Real time structural health monitoring system for a long span cable stayed bridge

Structural Health Monitoring System (”SHMS”) is to evaluate structural soundness based on correlation between excitations and responses, and additionally, is to detect structural deterioration and performance degradation analyzing tendency of the chronological transition. This paper presents an actual result of the SHMS for a long span cable stayed bridge including major purposes of the SHMS, applied sensor arrangement, total evaluation system and trigger values in conjunction with structural analysis
