EXPERIMENTAL STUDY ON RATIONALIZATION OF DESIGN FOR PILE CAP USING PRECAST PILE EMBEDMENT METHOD

In general, the width of precast pile caps is often set at 2.5D (D：pile diameter ). Numerous experiments on specimens with 2.5D have also been reported in previous studies. Furthermore, according to the literature from the Architectural Institute of Japan, the effect of shear reinforcement cannot be considered in the design formula of the pile head embedded portion. In this study, bending shear experiments were conducted using specimens with a pile cap width of 2.0D to present the damage process of the pile caps and the influence of various parameters on the experimental results. Additionally, by considering the effect of shear reinforcement, a proposed formula is presented to evaluate the maximum strength of the pile head embedded portion.
