Project Number 314
Date of Summary June 01, 1999
Subject Continued Development of Earthquake Load and Resistance Factor Design Guidelines
Performing Activity Ocean Engineering Services
Principal Investigator Dr. Robert Bea
Contracting Agency Minerals Management Service
Completion Complete
Description This project will continue development of the earthquake Load and Resistance Factor Design (LRFD) guidelines for offshore structures.  The focus is on three topics:  1) concrete Gravity Base Structures, 2) seismic hazard characterizations, and 3) verifying of the proposed ISO guidelines. The unique characteristics of concrete gravity based platforms will be addressed, including seismic loading considerations and soil-structure interaction. The results of selected seismic hazard studies will be reviewed to determine the accuracy of the guidelines for specifying the design spectrum.
Progress The final report (Benchmark Platform and Site Studies) was published and distributed to the participants.  Based on the information obtained from this study, a first generation LRFD/ISO guideline for design of steel, pile supported, template-type platforms to resist earthquake induced loading was developed and submitted to the ISO-P5 committee member for consideration.
