RECOMMENDATIONS FOR STRUCTURAL DESIGN OF PILE CAP FOR SINGLE PILE WITH HORIZONTAL TWO-WAY ECCENTRICITY

Abstract

The stress transferring mechanism of single pile caps with horizontal two-way eccentricity was investigated using FEM analysis. Since the compressive stress of the pile cap is lower than that of the column except local points, the safety of the pile cap can be ensured by making the concrete strength of the cap and column the same. Moreover, high shear stress and strain were observed in the foundation beams toward the inside of the building. Therefore, the shear design of foundation beams connected to the caps requires a margin of concrete strength and stirrup.
