Shear Strength of Atypical Reinforced Concrete Pile by Permanent Uni-Wall System

Abstract

The cross section of Permanent Uni-Wall System (PUS) is formed by circular casing and special casing. As for the special casing cross section of PUS, it is difficult to calculate the shear strength because of atypical section. This study conducted a shear test for three specimens, the variable of which is the shape of the PUS cross section, without the shear reinforcing bar. The test results showed that the shear strength of the specimens had a resisting force larger than the nominal shear strength by ACI318. It was also found that the specimens of PUS’s special casing cross section and the specimen of the equivalent rectangular cross section had a similar level of shear strength.
