Wave Force on Buildings
Historic rock-mounted lighthouses play a vital role in the safe navigation around perilous reefs. However, their longevity is threatened by the battering of waves. Through the paper, after a site-specific extreme wave characterisation, the study evaluates the dynamic response of Fastnet lighthouse under the action of different wave loadings by means of a validated FEM numerical model. Validation is carried out by comparing the numerical modal parameters and the results of the offshore field modal test. The aim of the study is to provide a comprehensive survivability assessment methodology for this type of structure.
