Offshore monopile foundations are exposed to misaligned wind and wave loadings, which respectively dominated by (nearly) static cyclic load components. While the response of these systems unidirectional loading has been extensively investigated, only a few studies have devoted realistic case loads, particularly effects such misalignment on accumulation pile rotation under prolonged cycling. Thi...

It is very difficult to predict the load carrying capacity of bored piles because of the Complications that may arise such as difficult ground conditions , presence of ground water, method of boring, method of concreting, quality of concrete, expertise of the construction staff, the ground conditions and the pile geometry. Therefore the Pile design must be accompanied by in situ load testing. M...

This study aimed to evaluate the p-y behavior of pile foundations installed in saturated silty sand subject cyclic lateral loading. Model piles were with three relative densities (40%, 70%, 90%), and loads magnitudes repeatedly applied. The model test results revealed that as loading was applied piles, soil around became densified loose (relative density 40%), stiffness curve increased. In cont...

Abstract The innovative technique of a hybrid PVD timber pile as vertical drain can be implemented to reinforce and improve soft soil. In this case, the acceleration pore water dissipation could increase shear strength. at soil study is investigate effectiveness eucalyptus pellita-PVD drain. test method applied laboratory model test, consisting installation on in rectangular pattern with spacin...

The application of prefabricated bridge structures is great significance to building industrialization, which can realize the green construction and maintenance process low energy consumption emission as well normal operation transportation in time, effectively development requirements. However, substructure a conventional usually needs cast bearing platform between pier column, may not give fu...

Slab-on-pile SOP viaducts have been constructed on several highways and railways in Indonesia, but there are certain doubts about some practical structural seismic design concepts. Therefore, this study aims to investigate the performance of a single spun pile column for viaduct using nonlinear analysis. The essential variables used include effect top reinforced concrete infill treatment, soil-...

ports are the most important economic, political and military bottlenecks. this puts shoreline structures (port) in the class of important structures and they have a crucial role in the countries’ life. pile and deck wharf and their access bridges and offshore deck (jetties), are one of the parts which are supplier of coupling between the land and the waterfront. correct and exact estimation of...

A parametric study was carried out to study the behavior of offshore anchor piles under mooring forces in dense sand using a three dimensional (3-D) finite element model (FEM). The Mohr–Coulomb plastic model has been used to model the soil, and has been calibrated based on the centrifuge tests discussed in a Ph.D. thesis (published by Ramadan in 2011). The selection of model parameters and comp...

In order to understand the load sharing and settlement reduction behaviour of piled raft resting on soft clay, 1g model tests were conducted on small-scale models. The parameters studied were the effect of pile length and number of piles. The load settlement behaviour obtained from the tests has been validated using simplified method (Polous & Davis). Equivalent pier concept of Poulos and Davis...
