CONTENTS

Waterfront and coastal concrete marine structures are exposed to severe environmental conditions for which concrete is ideallysited. These condirioms inciade wind; waves inclading seichex and tsanamis; ice and ship inpact; abrasion and impact fromfloating debris;: passing vessel effects; and seismic evens. As many of these strucfures are pile-sapported the seismic loing can becritical and therefore α discassion of piles and their installationis inchnded in rhis guide. Aiso provided are fhe measuwres rhat can be taken fo minimie the andesirable effects of these eviromentalfactors and reduce the potential for serious problems.

CHAPTER1-GENERAL

1.1-Introduction

The use of properly designed durable and sustainable structures. Except for some criteria in ACI 357R and special- concrete is an economical approach to the design of marineized criteria in other ACI guides on durability there are noprehensive guidelines or standards that cover the appli- cation of concrete in the marine environment for coastalmarine structures. Current building codes and ACI standards do not address the requirements unique to the design ofthese structures with the exception of special applicationsor requirements for piles and concrete durability This guide provides design guidance for the use of concrete for coastalmarine structures and is intended to plement other design manuals and guides used for this purpose.

1.2-Scope

This guide primarily covers marine structures usedfor berthing marine vessels in protected harbors and for supporting the associated loads. Structures covered by thisguide include pile-supported platforms bulkheads andgravity structures. It is not intended to cover marine struc- tures such as gravity block wall tunnels breakwaters on special considerations for marine concrete and guid- floating structures or offshore platforms. Emphasis is placedance for the design and construction of marine structures.Because of the severe nature of the marine environment and associated loading conditions certain remendations inthis report are intended to plement the requirements ofACI 318.

Existing design guides are used for basic concepts load-ings marine hardware and other criteria that affect the use of concrete in marine structures. There are some pre-hensive manuals that cover functional and structural guide- lines for the design of coastal marine structures (MIL-HDBK-1025 2006; BS 6349-1 to 8; Goda et al. 2009: EAU2004; Ports Customs and Free Zone Corporation 2007: Werner 1998; FEMA P-55 2011.

Hard (Calcar-eous) fouling organisms include barnacles encrusting bryo- zoans mollusks polychaete and other tube worms andzebra mussels.
