SUMMARY:

The test methods for determining the post-cracking behavior parameters of Steel Fiber Reinforced Self-Compacting Concrete (SFRSCC) have been constantly improved. The Semi-Circular Bending Test (SCBT) for this composite is a new proposal that is promising and shown important advantages such as the possibility of carrying out the test on cores extracted directly from the structural element and the low cost and simplicity of carrying out. However, the literature on this topic is still scarce. This work aims to propose a new test, hereinafter called Modified Semi-Circular Bending Test (MSCBT), which is a modified version of the SCBT, through an experimental program involving innovations such as: the monitoring of the Crack Mouth Opening Displacement (CMOD), the study of sample dimensions, the influence of different types and contents of steel fibers, as well as the type of concrete and the comparison with other tests already well covered in the literature for the same purpose. A computational algorithm for carrying out the inverse analysis progressive procedure is developed and its results compared with those of different literatures. A validation of the testing methodology is performed using Finite Element Method (FEM) Software.
