Numerous techniques have been presented by different researchers to analyze piled raft. In order to analyze pile foundation, soil can be modeled as spring, continuous medium, or porous media. Pile can also be modeled as spring or continuous medium. This study includes three main stages: a short description of different types of analysis methods of pile foundation, writing a computer program bas...

This research investigates the influence of pile spacing on dynamic behavior groups by performing a series specifically designed centrifuge experiments foundations embedded in two-layered soil profile. A single and two 3×1 row with different were used as model foundations, models consisted soft clay underlain dense sand. The earthquake frequency soils is discussed using data 1D site response an...

Six buildings were overturned in the town of Onagawa during the 2011 Great East Japan tsunami. This study investigates the possible failure mechanisms of building overturning during tsunami flow. The tsunami inundation depth and flow velocity at each overturned building were recalculated by using a tsunami numerical simulation and verified using a recorded video. The overturning moment is a res...

In this paper, the shaking table tests of a Seismic–Soil–Pile–Superstructure Interaction (SSPSI) in medium-soft and hard base soil were carried out. Silted clay with unit weight 1.70 g/cm3 shear wave velocity 175 m/s was adopted to simulate soil, while composite obtained by adding 20% quicklime silted 1.75 300 tests. By inputting artificial seismic motion time history different amplitudes synth...

The present study aims to obtain p-y curves (Winkler spring properties for lateral pile-soil interaction) liquefied soil from 12 comprehensive centrifuge test cases where pile groups were embedded in liquefiable soil. curve fully is back-calculated the dynamic data using a numerical procedure recorded response and strain records instrumented pile. obtained two ground conditions: (a) spreading o...

The stiffness and damping of pile foundations are proposed, which vary with the ratio of shear modulus Gi / Go to indicate the nonlinear properties of soil. The range of Gi / Go is defined with different vibration intensities for applications, and a computer program DYNAN is available based on the boundary zone model with non-reflective interface. Two engineering cases are studied to illustrate...

An overview of offshore wind turbine (OWT) foundations is presented, focusing primarily on the monopile foundation. The uncertainty in offshore soil conditions as well as random wind and wave loading is currently treated with a deterministic design procedure, though some standards allow engineers to use a probability-based approach. Laterally loaded monopile foundations are typically designed u...
