초록
In offshore structures, fire is one of the most important hazardous events. The concern of fires has recently been reflected in therules and quantified risk assessment based design practice. Within the framework of quantified risk assessment and the management of offshoreinstallations, therefore, more refined computations of the consequences or hazardous action effects due to fire are required. To mitigate fire risk,passive fire protection(PFP) is widely used on offshore structures. This study presents methods for a nonlinear structural response analysisconsidering the PFP effects under fires. It is found that a structural response analysis is most likely to use valuable technology for the optimizationand design of offshore structures with PFP. Thermal and structural response analyses have been performed using LS-DYNA and FAHTS/USFOS. The results of these structural response analyses are compared with each other.
