| ACI | 1984 | 23 |
The report provides a guide for the design and construction of fixed reinforced and/or prestressed concrete structures for service in a marine environment. Only fixed structures which are founded on the seabed and obtain their stability from the vertical forces of gravity are covered. Contents include: materials and durability; dead, deformation, live environmental, and accidental loads; design and analysis; foundations; construction and installation; and inspection and repair. Two appendices discuss environmental loads such as wave, wind, and ice loads in detail, and the design of offshore concrete structures for earthquake resistance. Keywords: anchorage (structural); concrete construction; construction materials; cracking (fracturing); dynamic loads; earthquakes; earthquake resistant structures; foundations; grouting; harbor structures; inspection; loads (forces); ocean bottom; offshore structures; post-tensioning; prestressed concrete; prestressing steels; reinforced concrete; repairs; static loads; structural analysis; structural design; underwater construction.
