Monotonic and cyclic tensile behaviour of steel fibre reinforced concrete

In this research, in order to investigate the uniaxial tensile behaviour of steel fibre reinforced concrete (SFRC) under monotonic or cyclic loading, an extensive experimental program has been conducted. The test variables were concrete compressive strength, fibre volumetric ratio, and fibre aspect ratio (length to diameter). From the comparison of the test results with various SFRC tension models, it was invest igated that the Diverse Embedment Model (DEM) showed the best agreement with the monotonic tension test results. From the cyclic tension test results, the variation of the stiffness for un- and reloading paths has been investigated, which can be valuable to develop SFRC cyclic tension model.
