ANALYTICAL AND EXPERIMENTAL STUDY OF FLEXURAL STRENGTHENING OF RC MEMBERS USING MECHANICALLY FASTENED FRP STRIPS

摘要

The main objective of this work is to investigate the behaviour of reinforced concrete members strengthened for flexure using mechanically fastened fiber reinforced polymer (FRP) strips. Experiments were conducted on strengthened reinforced concrete beams loaded to failure with an increasing load in four-point bending. An analytical-numerical model was developed predicting the behaviour of the strengthened concrete beam and reproducing its large ductility before failure.
