Indian Concrete Journal - ICJSummary: In this paper, an effort is made to understand the shear mode of failure of concrete filled un-plasticized polyvinyl chloride tubular (CFUT) columns with the help of Mohr-Coulomb failure criterion. The analytical results are verified with experimental results. The effect of confining pressure on angle of shear failure plane has been investigated, presented, and discussed. To understand the failure mechanism, eighteen specimens of concrete filled unplasticized polyvinyl chloride (UPVC) tubular columns were cast by filling concrete of grade M30 and M40 in the tubes of diameters 160, 200, and 225 mm of class 3, 4 and 5 with nominal pressure of 0.6, 0.8, and 1.0 mPa [as per IS: 4985 (2000)[12]. All the specimens were tested by applying axial load on concrete core only. It was found that all the specimens failed by development of shear cracks with slight bulging. Mohr-Coulomb failure criterion was used to calculate the angle of failure plane. Present study shows that shear failure of CFUT columns may be avoided using UPVC tubes of higher class.
