This paper presents an evaluation of shear failure mechanisms in reinforced concrete (RC) pile supported footings by using a nonlinear numerical analysis. A rigid-body-spring model, which is one of discrete type approaches, is used to analyze shear failure behaviors of RC footings. The numerical model predicts the three dimensional crack development and the punching shear capacity, and is validated by comparison with experimental observations. Sensitivity analyses are conducted to study the effect of longitudinal reinforcement arrangement that affects productivity of reinforcement placement in construction.
