Relationship between Deflection and Crack Mouth Opening Displacement of Self-Compacting Concrete Beams with and without Fibers
There are only a few research results for predicting the relationship between deflection and the crack mouth opening displacement (CMOD) of self-compacting concrete (SCC) beams with and without fibers. A series of bending beam tests on SCC, with different fiber types have been carried out. For this purpose, four SCC mixes—plain SCC, steel, polypropylene, and hybrid fiber reinforced SCC—are considered in the test program. Based on the experimental results, a model for predicting the relation between the deflection and CMOD of SCC has been established per each mix. These models rely on the load–deflection relation and the load–CMOD relation of bending beam. A well agreement has been found between the suggested model and the test results. The results of this study indicate that the load–deflection diagram is very similar to that of the load–CMOD diagram, and there is a linear relation between the mid-span deflection and CMOD of SCC.
