Modeling of Tensile and Shear Mechanical Properties of Steel Fiber Reinforced Concrete

Abstract

The mechanical properties of steel fiber reinforced concrete subjected to tension and shear are investigated experimentally and their mathematical models are presented. High-strength concrete is used for specimen. The angle between a fiber and the crack surface is considered as a main parameter. The tensile behavior is influenced by the fiber angle. The maximum load is reduced when the fiber is not perpendicular to the crack surface. For shear loading, the maximum load is also reduced when the fiber direction is opposite to the shearing direction. These experimental results are expressed by using the multi-linear nonlinear model and the parallel structural model simultaneously and the validity of the modeling is confirmed through simulation.
