Book Description
Describes work conducted to examine issues related to the CSA/CAN S474 Code for Fixed Offshore Concrete Structures, divided into two phases: examination of the appropriateness of the 1.35 load factor specified for use on the 1 in 100 year iceberg for the design of the concrete strength; and examination of the load combination factors specified in the Code for rare environmental events occurring along with companion frequent environmental events. Sections describing phase I discuss the principles and computer programs used to determine iceberg loadings, the design of a force analysis model and the subsequent force analysis, analyze the structure for the reliability level under iceberg loads, and present an economic analysis for the different load factors. Sections describing phase II discuss methodology and theory used to calculate environmental loads, introduce computer analysis methods, and present analytical results including final calculated environmental loads and resulting calculated load combination factors.
