This paper presents novel measurement data on the dynamic soil–structure interaction of an end-bearing pile foundation. The purpose is to assess ability predict foundation impedances based small-strain properties soil obtained from site investigations. Measurements were performed in two stages construction, allowing between piles through soil. First, single and factors experimentally for four w...

Neisseria gonorrhoeae and N. meningitidis are obligate human pathogens of medical importance which are highly related at the genomic level and have a conserved array of pathogenicity determinants (Virji, 2009). N. meningitidis resides in the human nasopharynx and is the causative agent of transmissible meningitis and septic shock (Stephens et al., 2007). N. gonorrhoeae is a resident of the urog...

Sand dripping in 1 dimensional Sand Pile Model is rst studied. Patterns and signals appear. Their behaviors and interactions are explained and asymptotic approximations are made. The total collapsing time of a single stack of sand is linear in function of the number of grains.

in this paper effect of pile-soil consideration in obtaining seismic response offshore structure is assessed due to earthquake loading. inducedseismic force is one of the most important excitations for the dynamic response of an offshore structure. according to api, seismic forces should be accounted in platform design for seismically active regions in order to determine the allowable seismic r...

Recently, have been applied widely in infrastructure Indonesiam especially if the new building was built around another building. Therefore, bore pile is considered most suitable for this case. In research, which ere previously existing condition as group drilled piles were modified into single pile. The result of study indicate that use borepile very safe terms bearing capacity, deflection and...

For pile foundations subjected to lateral loads, an analysis method should account for the response of the combined soil-pile system. Current practice for pile-soil interaction analysis usually employs a series of springs to model the lateral behavior of soil-pile interaction. In this method, the force (p) – deformation (y) function, widely known as p-y curve, of the spring characterizes the pi...

This paper presents the application of the Artificial Neural Network (ANN) for prediction of axial capacity of a driven pile by adopting data collected from several projects in Indonesia and Malaysia. As many as 300 data were selected for this study. In this study, ANN was set and trained to predict the axial bearing capacity from high strain dynamic testing, i.e. Pile Driving Analyzer (PDA) da...

Abstract: According to the Winkler assumption, the form of the pile constraint could be simplified as bottom fixing and top free. Considering the influence from resistance of soil around pile, the equations on calculated length for buckling stability of steel pipe pile when the portions along the pile length were constrained in the uniform foundation and the layered foundation were respectively...

Estimating pile group efficiency for open-ended steel piles in small arrangements is a challenging task designers. This paper reports on the large-scale experimental campaign performed BorWin gamma offshore converter platform, which involved single and two-pile systems scale of 1:10. The works included installation, dynamic end-of-driving tests, restrike static load tests pair groups densely co...
