Structural reliability assessment based on optical monitoring system: case study
AbstractThis work aims to present a case study on structural health monitoring focused on reliability assessment and applying data collected by a simplified optical sensing system. In this way, an elevated reinforced concrete water reservoir was instrumented with a bi-axial optical accelerometer and monitored since January 2014. Taking into account acceleration data, the natural frequencies and relative displacements were estimated. The reliability analysis is performed based on generalized extreme values distribution (GEV), and the results are compared with another two probabilistic methods, namely normal probabilistic distribution and lognormal probabilistic function. The results show that the optical system combined with GEV analysis, implemented in this experimental work, can provide adequate data for structural reliability assessment.
