Prestressed concrete piles with closed-ended circular hollow sections (spun piles) are sometimes used as foundations for pile-supported wharves. Due to a reduction in the rebar area, compressive strength, yield strength of PC-bar, and bond between PC-bar concrete, corrosion attacks typically lower performance spun marine environment. A comprehensive analysis effect on mechanical properties pile...

The dynamic characteristics of the flow around pile directly determine distribution law force on pile, which is basis calculation load hydraulic structure. At present, model test and numerical simulation methods are mainly used to study pile. There problems scale effect accuracy in laboratory test, inherent method, such as determination medium parameters, mesh division, boundary conditions. The...

Nonlinear dynamic analyses were performed to evaluate the effects of ground motion duration on response a pile-supported wharf subjected liquefaction-induced lateral deformations. The numerical model was first calibrated using recorded data from well-instrumented centrifuge test, after which incremental conducted suite spectrally matched motions with different durations. nonlinear evaluated thr...
