The Influence of the Prestress of Reinforced Steel on the Behaviour of the Flexural Elements of Reinforced Concrete

Abstract

This article briefly discusses the essence of prestressed concrete,its advantages and disadvantages. The analysis of prestress lossesis done according to different standards. The paper explainspretensioning force and selection of its eccentricity as well asanalyzes the influence of beam cracking according to limitationson concrete tensile and compressive stresses.
