EFFECT OF SHAPE OF MAIN REINFORCEMENT IN SLABS

In civil engineering design and construction the ma in steel in beams and slabs are used to take the tension and to increase the ductile behavior. In slabs the main and distribution steel is provided in horizontal form. Also the main steel in singly reinforced and doubly reinforced beams is in horizontal form only. But if we replace this horizontal form of the reinforcement in beams and slabs by rectangular trough, trapezoidal trough or V shaped, there will be increase in the moment carrying, shear carrying capacity with reduced deflection because of folded plate action and thereby the sections becomes more economical.
