Modeling of steel fibres as flexural cracks inhibitor in reinforced concrete beam

Flexural cracks are most common problem on structural members which are subjected to bending moments. the introduction of steel fibres in concrete beam has been proposed as flexural cracks inhibitor. this research was conducted focusing on simply supported beam to determine the crack propagations in flexure by varying the 25 kg/m3 steel fibre content placement in the beam. the results showed stress patterns from ansys software are similar to the experimental findings with minimal magnitude difference of about 11 %. it is concluded that the steel fibre inhibits flexural cracks and delayed the flexural failure in beams as depicted in the experimental results from 11 beams. © 2015 penerbit utm press. all rights reserved.
