By using IRC Standard the design of deck slab is done by Transverse Analysis by Live Load Calculations with Effective width method. Design is checked for Ultimate Limit State (ULS) and Service Limit State (SLS) conditions. The Design of PSC I-Girders is done for Bending moments and Shear forces by Dead Load, Super Imposed Dead Load (SIDL) and Live Loads (LL). The Shrinkage strain, Creep Strain and effect of Temperature rise and fall are also determined. The design is complete for Pre-stressing cables, End anchorages, un-tensioned reinforcements, End cross girder, Shear connectors. 4.0 General Pre-stressed concrete is not a material rather it is a reinforced concrete structural member in which internal stresses of a suitable magnitude and distribution are introduced so that the stresses resulting from external loads are resisted to desired degree. In reinforced concrete members, the pre-stress is commonly introduced by tensioning the steel reinforcement. The development of early cracks in reinforced concrete was due to incompatibility in the strains of steel and concrete. This was perhaps the starting point in the development of the "Pre-stressed concrete". The application of permanent compressive stress to a material like concrete, which is strong in compression but weak in tension, increases the apparent tensile strength of that material, with an intension that the subsequent application of tensile stress must first nullify the compressive pre-stress. By using high strength concrete and steel in 'pre-stressed' members results lighter and slender members than that by ordinary reinforced concrete members. In fully pre-stressed members, the member is free from tensile stresses under working loads, by making the whole of the section effective and dead loads may be counterbalanced by eccentric pre-stressing. There are certain disadvantages in implementing pre-stressed concrete, which include: the less availability of experienced builders, high initial equipment cost, less availability of experienced engineers, pre-stressed sections are commonly brittle and pre-stressed concrete sections are weak in fire resistance because of tendon cables.
