This paper presents preliminary results of a more extended experimental program on mechanical behaviour of fibre reinforced polymer (FRP) reinforced concrete (RC) beams. Two beams internally reinforced with GFRP bars are tested under a quasi-static four-point bending configuration. Displacement and strain values measured through the implementation of a three-dimensional digital image correlation (3D-DIC) system are compared to those recorded by well-established point wise transducers (strain gauges and potentiometers) and the quality of the full field, optical measurements is discussed and commented upon.

Abstract

This paper presents preliminary results of a more extended experimental program on mechanical behaviour of fibre reinforced polymer (FRP) reinforced concrete (RC) beams. Two beams internally reinforced with GFRP bars are tested under a quasi-static four-point bending configuration. Displacement and strain values measured through the implementation of a three-dimensional digital image correlation (3D-DIC) system are compared to those recorded by well-established point wise transducers (strain gauges and potentiometers) and the quality of the full field, optical measurements is discussed and commented upon.
