Load Sharing Benefits of Composite Pile Systems

by Harry Burn,

Document Type: Proceeding Paper

Part of: World Marina '91


The paper develops design techniques which will allow piled systems to be extended into more onerous operating conditions. In storm events marinas always develop failure mechanisms at structural joints and in the past this has been 'overcome' by the use of additional piles which while increasing the cost may in fact provide a negative impact on the structural safety of the marina. The paper develops a basic theory to ensure a full load sharing throughout a marina thus minimising transferred loads within a deck system. The practical limitation of water depth for a commercially viable piled system is extended to approximately 80ft. Alternative methods of construction are discussed and the possibility of extension of the theory to commercial maritime structures is described.
