Abstract: In the present paper experimental results relating to flexural tests on reinforced concrete corbels subjected to vertical forces are presented. The effects of the following are analysed: longitudinal and transverse steel reinforcements; fiber reinforced concrete (FRC) with hooked steel fibers; external wrapping retrofitting technique with a thin layer of carbon fiber sheet (CFRP).
The results obtained in terms of both load-deflection curves and cracking and failure modes highlight the fact that by using FRC or CFRP it is possible to obtain performances comparable, in terms of maximum strength and ductility, with those of corbels well confined with transverse steel. Moreover, the use of FCR instead of plain concrete allows more simple realisation, and the use of CFRP as a retrofitting technique of existing members allows one to simplify the procedures required in traditional retrofitting techniques.
