The structural behaviors of cast in place reinforced concrete piles are different from those of super structural members in shear and flexure. Since there is no reliable equation for estimating the shear strength of cast in place concrete piles, shear-flexural tests were conducted with double bending type specimens. The test results showed that the shear strengths calculated from the modified Ohno-Arakawa equations are relatively in good agreement with the test data. The deformational characteristics varied with the shear reinforcing ratios. The specimens exceeded the ultimate flexural strength showed enough performance in displacement. The shear strength became higher considerably when the axial load was applied to the specimens. It is necessary to consider the effect of axial stress in equations for estimating the shear strength of concrete piles.
