Abstract:This work compares the experimental and theoretical results of a new formulation for the design of precast column bases embedded in socket foundations with smooth interfaces. Through the proposed strut and tie model, the longitudinal and transverse reinforcements of column are calculated, and concrete crushing is verified. The proposed design model was rather rational in the reinforcements design, and its results were very close to experimental results. These latter results were generated from two specimens with smooth interfaces submitted to a normal load with large eccentricity, varying the embedded lengths. For loads with small eccentricities, a simplified model is proposed, which neglects the friction of interfaces and the eccentricity of normal reaction at the column base.
