An experimental investigation on flexural behaviour of stainless steel fiber reinforced concrete beam elements

Abstract

Concrete is the most widely used construction material because of its specialty of being cast into any desirable shape. Ductility and energy absorption capacity are the main requirements of earthquake resistant structures. However the conventional concrete has low tensile strength, lower energy absorption and little resistance to cracking. Therefore, it cannot fulfill the requirements of the earthquake or seismic resistant structure. Extensive researches have shown that the most significant influence of the inclusion of steel fiber in concrete is to delay and control tensile cracking of the composite material. The primary variables are fiber content and matrix composition. The addition of steel fiber to matrix leads to improvement in several properties of concrete. In this investigation the strength properties are determined by using different geometrical steel fibers. The various parameters like load carrying capacity, stiffness, ductility character and energy absorption capacity has to be analyzed.
