Strain measurements in reinforced concrete walls during the hydration reaction by means of embedded fibre interferometers

摘要: In a reinforced concrete wall the deformation during hardening was measured by means of embedded extrinsic fibre-Fabry-Perot-interferometers. The sensors were specifically modified in order to provide self-calibration cycle and ensure functional efficiency under adverse conditions at building site. installation done wall's cage reinforcement before its concreting. measurement carried out automatically over period 35 days. measuring results are very satisfactory give resolution 0.1 micrometers /m.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
