Prestressed concrete

The study aims to provide an in-depth awareness of the loading capacity, deflection characteristics, and failure mechanisms exhibited by these girders by applying finite element analysis (FEA) techniques.

This paper presents an experimental study on the effect of prestressing force on the flexural behavior of unbonded prestressed concrete (UPC) strengthened by Carbon fiber reinforced polymer (CFRP) sheets. The testing program was carried out on nine large-scale UPC rectangular beams.

This article evaluates and compares the punching shear behaviour of unbonded prestressed concrete (UPC) slab - concrete-filled steel tube (CFT) column connections/joints with that of reinforced concrete (RC) slab – CFT column connections. The experimental program was carried out on five large-sized samples, including three UPC slab - CFT column samples and two RC slab - CFT column samples.

The application of prestressing steel is restricted in highly corrosive environment area due to corrosion of prestressing steel, which leads to reduction in strength and it may cause sudden failure. Carbon textile is considered as an alternate material due to its corrosive resistance property, high tensile strength and perfectly elastic. In this study, an experimental investigation was carried out to study the flexural behavior of prestressed and non-prestressed carbon textile reinforced concrete plates.
