Manual mechanical prestressing system of thin shallow curved slab

Abstract A manual mechanical prestressing system was manufactured which used to apply a post-tension force the high-stress steel wires in curved slab member. The study aims experiment with use of technique thin sections assess prestressed influencing behavior at initial and final loading stages. Two advantages achieved system; pulling all positions simultaneously application perpendicular cross-section slab. To check efficiency system, two reactive powder concrete members were cast tested under uniformly distributed load. first one is reinforced micro fibers while second addition four wires. experimental results showed applicability facility using this perform forces slabs. Applying member increased cracking ultimate loads about 311% 381% respectively compared non-prestress slab, whereas failure mode occurred by flexural-tensile stress near edge beams for both
