THE APPLICATION OF STATICS TO END ZONES OF PRESTRESSED BEAMS
Ever since the early development of pre-stressed concrete considerable effort has been expended on the stress analysis of the end zone. However, the significance of an idealised elastic stress distribution in terms of reinforcement in a non-elastic, non-homogenous cracked block of reinforced concrete has received little attention. This paper advocates the determination of the stress resultants (i.e. bending moments and direct forces) which are required to transfer concentrated loads to distributed loads, within the end zone, from statics. End zone reinforcement is then determined directly from these stress resultants, to provide the required capacity. The elastic stress distribution then has the secondary role of providing a guide to the most effective positioning of reinforcement. That is the position which requires the least degree of plastic redistribution to permit the reinforcement to develop its design stress in resisting these statically determined stress resultants. /Author/
