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

Bridge Design For Earthquake Fault Crossings: Synthesis Of Design Issues And Strategies, Rakesh K. Goel, Bing Qu, Osmar Rodriguez, Jennifer Tures
Rakesh K. Goel
As shown by the bridge damages observed from recent earthquakes, the bridges crossing earthquake faults can be more vulnerable compared with those lying on one side of the earthquake faults. Avoiding building bridges across earthquake fault zones might be the best design strategy; however, it is not always possible to do so in regions of high seismicity such as California. While rigorous nonlinear response history analysis (RHA) using the spatially-varying ground motions generated based on site-specific seismological studies can be conducted for bridges crossing fault ruptures; such a design and analysis process is too onerous, making it less practical for …
