Circular reinforced concrete members are used for superstructure columns and foundation piles. The lateral reinforcing ratios of concrete piles are less than 0.2% and quite low compared with superstructure columns. Because of insufficient lateral reinforcement concrete piles were damaged by Hanshin-Awaji earthquake of 1995. There is little information about their seismic strength and also no reliable equations for estimating shear strength of circular reinforced concrete members with low lateral reinforcement. It is necessary to accumulate experimental data to establish the equations for estimating shear strength of foundation piles. Comparisons between experimental data and The Arakawa and ACI equations for superstructure columns were made to examine their applicability. The Arakawa equation was modified to adopt circular members. The modified Arakawa equation is in good agreement with the experimental data.
