CIVIL ENGINEERING Prestressed concrete is method for overcoming concretes natural weakness in tension. The SlideShare family just got bigger. THE FUTURE. Looks like youve clipped this slide to already. Prestressed concrete is a system into which internal stresses are deliberately induced without any form of external loads to improve its performance. The forced applied is the tensioning or stretching of the steel component which usually in the form of high tensile strands, wires or bars. The alternative to pre-tensioning is post-tensioning. Tendon: A stretched element used in a concrete member of structure to impart prestress to the concrete. Material properties, such as corrosion resistance, fire resistance and durability are being continuously improved and exploited. reinforced concrete. In this method, prestressing is induced (the tendons are tensioned) before the concrete is placed. Abstract: The concept of load balancing is introduced for pre-stressed concrete structures, as a third approach after the elastic stress and the ultimate strength methods of design and analysis. Different methods have been utilized to study the response of structural components. Clipping is a handy way to collect important slides you want to go back to later.
