Eurocode 1 - Actions on structures - Part 1-8: Actions from waves and currents on coastal structures
EN 1991-1-8 gives principles and rules to determine the values of wave and current actions on structures and civil engineering works in the coastal zone, i.e. works connected or in close vicinity to the shore. EN 1991-1-8 describes the principles for defining the design sea conditions, including design water level variability for structures in the coastal area. In EN 1991-1-8 the following structure types are specifically addressed: - cylindrical structures; - suspended decks; - sub sea pipelines; - breakwaters: - mound breakwaters; - vertical face breakwaters; - composite breakwaters; - coastal embankments: - revetments; - seawalls; - permanently moored floating structures. - floating platforms in the coastal zone related to oil and gas production or processing; - floating platforms in the coastal zone for renewable energy production. EN 1991-1-8 does not fully cover principles for determining actions from waves and currents on: - port structures like piers, jetties, quay walls, marine terminals in sheltered marine areas; - installations for mooring and berthing of ships. For hydraulic pressures on structural envelopes caused by quasi-static water levels, and for under pressures in the ground, see EN 1997 (all parts). EN 1991-1-8 does not cover: - tsunamis; - hydraulic consequences of an accidental breakdown of water actions from retaining structures; - waves from passing ships; - currents induced by jets or ship’s propellers; - coastal structures where flood risk and/or erosion or sediment management is the dominant function.
