Use of Steel Fibers in Crack Control and Earthquake Engineering

In any structural element the strength of element is governed basically through how much resistance that structure offers with external applied load. For better structure integrity a structure should perfectly form a matrix which may be able to resist load. A structure follows to break when crack formation takes place. A crack when form in structure it further increases may lead to structural break down. A tensile strength in structure is provided by steel reinforcement, but when there is crack formation it leads to further propagate and result to structural break down. To stop the crack formation, a mechanism that stops to wide crack formation or a mechanism that arrest crack and lead structure not to widen up is possible by steel fiber. A steel fiber is that material which provides crack arrest and is very useful in controlling cracks. It is very useful earthquake resistance material. In this paper we will discuss how steel fiber use in crack control and how it used in earthquake engineering. Steel fiber improves property like tensile strength, toughness, post cracking behavior, impact resistance, and flexural strength. In this paper we discuss the technical matrix behavior that how it work on strength increase. An experimental work is done in which a specimen is without fiber and other one is with fiber and we perform comparative study in between .So that it may use as great earthquake resistance design material to provide lesser loss from earthquake.
