Abstract
The main purpose of this research is to investigate the flexural strength of reinforced ECC beams under static and repeated loading. Eighteen reinforced ECC beams with deferent fiber content and deferent steel ratio were constructed and tested by applying static and repeated loading. The experimental variables considered in this study include fiber content, steel ratio, and loading type (static or repeated). All beams were geometrically similar with the dimension of (120mm in width, 200mm in depth, and 1000mm in length) and the applied loads were subjected to the beams with two point loads and simply supported span. The experimental outputs divided into four parts: the first part concerned with the effect of fiber content on the load deflection curves. The second part focused on the effect of steel ratio on the load deflection curves. Furthermore, the third part studied the comparison between static and repeated loading. Eventually, the last part investigated the effect of fiber content and steel ratio on flexural toughness. In reinforced, with increasing fiber content (for the same flexural reinforcement) the sample will increase its flexural strength. In general, to increase the ultimate flexural strength, the addition of steel ratio has much higher effect than increasing fiber content. Finally, for identical reinforced ECC beams, the flexural strength will be lower when applying repeated load other than static one.
