Structural Observation of Long-span Suspension Bridges for Safety Assessment: Implementation of an Optical Displacement Measurement System

Abstract

This pape r addresses the implementation of an optical displacement measurement system in the observation scenario of a long-span suspension bridge and its contribution for structural safety assessment. The metrological background required for quality assurance ofthe measurements is described, namely, the system's intrinsic parameterization and integration in the SI dimensional traceability chain by calibration, including its measurement uncertainty assessment.
