| Abstract | This investigation deals with the study of the stability of flexural cracks in singly and doubly-reinforced concrete beams. The analysis is based on assumed stress-strain curves for the concrete and steel. Tests were conducted on six rectangular reinforced concrete beams subjected to two point loads. The span and cross-sectional dimensions of the beams were kept constant. For singly- reinforced beams, the tensile reinforcements were varied and for the doubly- reinforced beams the compression reinforcements were kept constant while the tensile reinforcements were varied. All specimens were tested to destruction. It was observed that the stability of flexural cracks in reinforced concrete beams is a function of the tensile strength of concrete and the amount of tension reinforcement. The influence of compression reinforcement in stabilizing the propagation of cracks is not very significant. The experimental results obtained compares favorably with theoretically predicted values. |
