In Steel-concrete combined development solid uses for compressive quality and steel is for rigidity. When both steel and concrete are tied together they acted as a unit which is highly efficient and light-weighted. This type of steel solid composite generally utilized for structures, for example, spans and multi-story structures. In the steel concrete composite construction shear connection plays a very important role. In this paper, simply supported steel concrete composite beam design with optimal spacing of headed shear studs. Headed shear studs are distributed with optimal spacing at L/4 and L/6 distances with end supports where shear force is maximum. Keywords: Optimal spacing of shear connectors, shear connectors, steel-concrete composite, shear strength, spacing of shear connectors, simply supported composite beam INTRODUCTION A structural member which is made up of two or more materials which act as a unit is called composite member, and steel concrete composite is the most common composite element in construction. Steel- concrete composite members are formed by bonding a steel member, i.e., I-section, to a concrete member, i.e., reinforced concrete slab, now these two members act as a unit. With the advantage of the high tensile strength of steel and high compressive strength of concrete, composite steel construction has gained rapid recognition in the past few decades. Overview The problem in constructing either with steel or concrete is that they have their own speciality. Steel members are fabricated with thin plates which are prone to local lateral buckling and fatigue. Therefore, in steel construction primary concern is to prevent failure due to buckling. While on the other hand concrete members are thick but weak in tension and also inclined to creep and shrink with time. In order to overcome these problems of concrete we placed steel reinforcing bars for that. Steel and concrete composite structural members are also subjected to the buckling of the steel element and tensile cracking of the concrete. Steel and concrete composites are also prone to failure of the bond between the steel member and the concrete member, which is known as debonding. The effectiveness of connection between the steel and concrete elements is responsible for the composite action. Thus, in the plan of composite steel and solid structures, we not just need to comprehend the conduct of the individual parts of the steel and cement, yet in addition the bond between these segments.
