Abstract

Pre-stressed concrete is a method for overcoming concrete’s natural weakness, i.e. tension. It can be used to produce beams, slabs, girders for heavy loading, longer span with effectively less depth and are light weight by providing the curved tendons and the pre-compression, a considerable part of the shear is also resisted.
Pre-stressed concrete sections are thinner and lighter than RCC sections, since high strength concrete and steel are used. Thinner sections in pre-stressed concrete results in less self weight and hence overall economy. Cracks do not occur under working loads in the pre-stressed concrete sections. Even if a minute crack occurs when overloaded, such crack gets closed when the overload is removed.
In this paper analysis and design of different types of prestressed concrete sections using pre-tensioning and post-tensioning methods is reviewed. Pre-stressing removes a number of design limitations that the conventional concrete faces. The deflections of the pre-stressed concrete sections are small as compared to the conventional concrete.
