Abstract

Concrete structures are often subjected to various types of static and dynamic forces. Fibre reinforcement improves the behaviour of reinforced concrete beams. Experimental investigations were made to study the response of steel fiber reinforced concrete beams under half cyclic loading. Fourteen beams, of which two were control beams, all having size of 150x225x1800 mm length are prepared using cement concrete grade M 30 and designed as under reinforced beam. Twelve beams are strengthened with the addition of straight steel fibres in different volume fraction of 0.5%, 0.75% and 1% for the aspect ratios of 65 and 80. The observations of ductility, rotational capacity and residual strength are compared with steel fibre reinforced concrete beams through hysteric load-deflection and moment-rotation curves. It was found that the provision of 1 % volume fraction of fibres with aspect ratio 80 has better performance in terms of 18% increase in ductility index, 5.4% increase in rotational capacity and 44% increase in residual strength. Steel fibre reinforced concrete beams have exhibited smaller crack width compared with control beams.
