APPLYING THE CONCEPT OF POST TENSIONING INHYBRID BUILDING BY USING ETABS

prestressedbeam is defined as beam that had internal stresses introduce to counteract to the degree desire, the tensile stresses that will be imposed in service. The stress is usually imposed by tendons of individualhard-drawn wires, cables of hard-drawn wires, or bars of high strength alloy steel. Compressive stresses can be introduced either by pre-tensioning or by post-tensioning. The current paper emphasizes on prestressed design of pre cast beam considering variousstage, lifting stage, erection stage. The paper also enclosed the various losses that takes place during prestress and after prestressing
