CHAPTER ONE

1.0   INTRODUCTION

        Steel is a man-made material containing 95% of iron. The remaining constituent are small amount of element derived from the raw-material use in the making of the steel, as well as other element added to improve certain characteristics or properties of the product (Marcus, 1964). Steel reinforcement are used generally in the form of bars of circular cross-section in concrete structure. They are like a skeleton in human body. Plain concrete without steel or any other reinforcement is strong in compression but weak in tension. Steel is one of the best forms of reinforcement to take care of those stresses and to strengthen concrete to bear all kinds of load. In steel reinforcement transverse is very important. They not only take care of structural reinforcement but also help main reinforcement remain in desired positions. They play a very significant role abrupt changes or reversal of stresses like earthquake etc. (www.acclimited.com).
