The Calculation Method For The Ultimate Shear Strength Of Large Diameter Phc Piles

摘要

Today, it is necessary to make clear the ultimate shear strength of the PHC piles. In this research, we propose an estimation formula to predict the ultimate shear strength on the PHC piles. The estimation formula shows that the ultimate shear strength is the total of the share of the concrete (τ1), the share of the spiral reinforcement (τ2), the share of the axial force (τ3), and the share of the concrete filled in the hollow part of the piles (τ4) the estimation formula got for the conformability to be better than the experiment formula in the past.
