Elastic stability of pile-supported wharves and piers

摘要: Abstract Elastic stability equations for idealized pile-supported waterfront structures were implemented in a parametric study that accounts coupling between lateral stiffness of the supporting soil, pile flexural stiffness, and factored gravity loads. Results are summarized as design aids could enable engineers to obtain estimates second-order lowest buckling axial load each by using simple arithmetic calculations. Through these, an expedite tool is provided classify two-dimensional pier/wharf frame fully braced or partially further allow estimating effective length factor, K, once equivalent column established. Three application examples presented demonstrate versatility method compare results with those from commercially-available finite element software. For case marginal wharf, slender waterside piles was found be smaller than short landside piles; however difference two became less significant when soil soft. It also determined level loads practice, plumb finger piers wharves commonly considered even if relatively
