![]() ![]() It is determined that due to lack of the specimens the large deviations of residual flexural tensile strength can be obtained and it can cause the significant errors of calculated crack widths. Calculated crack widths are compared to the experimental results. A scatter of the residual tensile strength which is obtained from three point bending test and its influence to the crack width is also reviewed briefly. Experimental cracking results of small cross section flexural members reinforced with steel fibre and ordinary reinforcement are also discussed. All these methods have been derived using Eurocode 2 provisions, which are intended to the members without the fibre. ![]() Three crack width calculation methods of steel fibre and ordinary reinforced concrete flexural members are discussed in this paper. The residual tensile strength which is used for crack width calculations should be obtained from tests. It is known that steel fibre can reduce the crack width of reinforced concrete flexural members however generally accepted crack width calculation method does not exist yet. ![]()
