Abstract

Performance-based seismic engineering is now an established technology for buildings that can be adopted for offshore platforms. The development of performance-based seismic design criteria and applicability of this method for fixed offshore platforms was discussed in this paper. An analytical example including the inelastic time history analysis was presented. Structural performance and performance based assessment results was then compared with API and ISO recommendations. The results demonstrated that the performance based assessment is more reliable and may improve the integrity of the design to resist earthquakes. The results also indicated a better match between ISO standard and performance based design for the example platform.
