Jun 01, 2017  Concrete strength plays an important role on the flexural performance of reinforced concrete beams as well as steel reinforced concrete beams. In this case, the compression flange width of the T-beam specimen was relatively large in the compression zone, which led to enough compressive capacity to balance the result of the tension force ...
