This study examines the capability of the Relevance Vector Machine (RVM) and Multivariate Adaptive Regression Spline (MARS) for prediction of ultimate capacity of driven piles and drilled shafts. RVM is a sparse method for training generalized linear models, while MARS technique is basically an adaptive piece-wise regression approach. In this paper, pile capacity prediction models are developed...

The numerical prediction of vibration in buildings due to underground railways involves modelling many physical phenomena. Not least these is the dynamic soil-structure interaction that exists between various elements system. majority existing models assume railway tunnel and building’s foundation negligible, with two sub-systems behaving as though they are uncoupled. This paper presents some i...

In order to study the characteristics of pile–rock action steel pipe driven pile in coral reef limestone stratum, at China–Maldives Friendship Bridge site was selected carry out indoor physical and model tests with red sandstone as control group. The test outcomes indicate following: (1) when substantial deformation is permitted, has a considerable strength dispersion, low post-peak stress decr...

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...

driven precast reinforced concrete piles (dprcp) is extensively used as a foundation for bridges constructed over canals in egypt in order to avoid the diversion of water canals. the objectives of this research include identifying the main activities of dprcp execution in the bridge-construction industry in egypt and the risk factors affecting them. in addition, assessment of the effects of the...

ABSTRACT: The problem of lateral load induced on piles under earthquake has been plaguing professional engineers, geo-technical investigators and researchers alike for quite some time. The normal practice is to ensure that the fixed base shear of column does not exceed the static shear load capacity of piles. The inertial and stiffness effect of pile is usually ignored in dynamic earthquake ana...

The standard penetration test (SPT) has been widely used because of its usability, economy, and many correlations with soil properties among other factors. In SPT, hammer energy is an important factor to evaluate and calibrate N values. To measure hammer energy, an instrumented SPT rod was developed considering that stress waves transferring on rods during SPT driving are the same as stress wav...
