Actions/loads on structures

  • A. L. Marshall


In the preceding chapter we considered various aspects of the sea’s behaviour. The problem for the engineer is how to translate these into quantified actions on structures so that fitness for purpose can be assured. Durability is considered elsewhere, here we consider static and dynamic loading. In the latter case, of course, response is an important factor so that load and effect form a system. Similarly, wave behaviour may be affected by the presence of the structure: through reflection from a wall, for example. Again, in dealing with a floating structure, the mooring system must be included as an integral part of the whole, and drift forces become important. Other forms of loading feature also: wave slam, wave slap, breaking waves, fatigue, to say nothing of the live and dead loads from equipment, stored liquids, surcharge, earthquake, ice, fire and tempest. The ancients’ notions of the elements, earth, water, air and fire, are not far removed from the catalogue we need to examine, given one or two additions.
