Abstract

Strengthening of reinforced concrete (RC) structures is often necessary due to the change ofusingor to enhance the strength of deteriorated existing RC structures attributed toaging and environmental effects. Interfacial bond between the existing RC member and thestrengthening layer is knownto be the main factor for any successful strengtheningtechnique. This study investigates the efficiency of utilizing high strength cementitiousconnectors in preventing the debonding of textile reinforced mortar (TRM) strengtheninglayer from substrate concrete of RC beams. An experimental program is developed to investigate the effect of strengthof mortars and the distribution of cementitious connectors onthe behavior of the strengthenedbeams.TRM comprising eight and sixteen textile basalt fiber layerswere utilized in these experiments. The results demonstrate the effectiveness of cementitiousconnectors on the failure mode of strengthened beamsby means of controlling the debonding of TRM. The increase in cracking andultimate loads is demonstrated due to the strengthening of RC beams using TRM.
