LATERAL LOADING TEST OF FULL-SCALED PILE FOUNDATION FOCUSED ON ULTIMATE BEHAVIOR

Relevance vector machine and multivariate adaptive regression spline for modelling ultimate capacity of pile foundation

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...

Static and Dynamic Lateral Loading of Pile Groups

Effect of Pile Foundation on Natural Frequency of Soil Layer

Free vibration of soil often occurs during earthquakes. Since the vibration caused by earthquake does not have (steady state harmonic vibration) continuity, the alluvium vibrates with its natural frequency between two natural seismic waves. This study evaluates the effect of piles on the period of free vibration of a soil layer using numerical method. In the first stage, using analytical equati...

The Effect of Lateral Loading Parameters on Monopile Behavior Based on Physical Modeling

Monopiles are the most common type of foundation for offshore wind turbines (OWT). Monopiles have been used in more than 80% of the offshore wind turbines. A monopile will be affected by millions of lateral load cycles during the operating period, which will cause its rotation and lateral deformation. The rotation and the deformation are dependent on the soil properties, monopile specification,...

A comparative study on pile group and piled raft foundations (PRF) behavior under seismic loading

Study on the seismic behavior of piled rafts and pile groups while the same amount of construction material and excavation is used in their construction, are the main objective of this research. The process where the raft interaction with soil can affect the seismic response and stress distribution is also discussed in the current study. By means, ABAQUS software was applied for the finite elem...
