Evaluation Of In-Ground Plastic-Hinge Length And Depth Recommendations For Piles In Marine Oil And Lng Terminals, Rakesh K. Goel

Rakesh K. Goel

This investigation evaluated the current recommendations for plastic-hinge length and depth for pre-stressed concrete and hollow-steel piles for different soil conditions typical of those in Marine Oil and LNG Terminals. Nonlinear behavior for both pile and soil were considered and MOTEMS specified strain levels were used to compute the pile capacity. All analyses in this study were conducted using OpenSees software developed at the Pacific Earthquake Engineering Research Center. The approach used in this investigation for estimating the plastic-hinge length and depth is similar to that used in development of current MOTEMS recommendations. This investigation led to several important findings …
