Strengthening of infilled RC frames by CFRP

A series of tests has been performed at I.T.U. Structural and Earthquake Engineering Laboratory, to examine the differences between the structural behaviour of infilled RC frames strengthened by CFRP fabric with different connection details. Five identical 1/2 scale, one storey-one bay brittle brick infilled reinforced concrete frame specimens have been tested under cyclic lateral loads. The reinforced concrete bare frame and plastered brittle brick infilled RC frame are essentially reference specimens. Three other specimens have been strengthened using CFRP fabric with different connection details. The comparative results including lateral load capacities, failure modes and energy dissipitation are presented in this paper.
