Popis: The aim of this work is to develop and validate a measurement technique for investigating and analysing stress and strain on civil structures reinforced with carbon fibre composites. The proposed sensing elements are Bragg's fibre grating strain sensors. In order to verify the performances of the proposed method, a comparison was made with the results obtained using a laser Doppler vibrometer. The measurement technique was used to study two historical buildings still in use. The vault of the "Elmi - Pandolfi" building in Foligno, and the wooden floor of the "Siaz Building" in Trevi, both located in the province of Perugia, Italy. Both buildings were reinforced with Carbon Fibre Reinforced Plastic (CFRP) after an earthquake.
