Structural Performance of Pile-cap With Eccentricity in Two Horizontal Directions Under Beam-bottom-tension Loading

Year: 2025

Type: article

Abstract: This study investigates pile-caps with eccentricity in two horizontal directions under loading that induces tension at the beam bottoms. Cracks developed between the tips of the pile bars on the tension side and those of the column bars on the compression side. Measured strengths were lower than those from conventional flexural analyses, particularly when the pile-cap depth was small and the anchorage lengths of the pile bars were short, despite sufficient anchorage-to-diameter ratio. The observed strengths were reasonably estimated by assuming a failure plane consistent with the observed cracks.
