Comparison between the Behaviors of Different Concrete Types in Various Shear Tests

Abstract

Abstract A comparison between three direct shear test specimens of (push-off shear specimens, FIP shear test, and inverted “L” shape shear failure plane) was investigated experimentally and numerically and cast using normal, high and ultra-high-strength concrete with the effect of steel fiber. This paper presents which shear strength analysis settings in which testing operation and arrangement of mold can be performed by the simplest and at the same rate guarantees stable and steady results. Many variables were chosen to investigate its impact on shear test and behavior. These variables are grade of concrete, steel fiber volume fraction, method of testing, type of loading and size of shear failure plane area. A comparison between experimental work and the finite element method offers a powerful and generic tool for studying the behavior of many structures by ANSYS program which can represent many structures. It was found that the inclusion of steel fiber enhances the ultimate shear capacity of the concrete compared to plain concrete and leads to ductile failure method, higher ultimate strength in addition to much enhanced integrity of structure.
