Research Abstract

Topographical study of the construction site is made to investigate the seismic wave amplification in 2 dimensional sense. The frequency domain analysis, the time domain analysis and their hybrid approach have been employed. The parameter used are the incident wave types, angle of incidence, topography, aspect ratio between wide and depth of the soil deposits. Analysis is conducted for representative nondimensional frequency. The Green function involved for the BEM analysis is developed for the concentrated as well as uniform distributed forces. The Fourier transform method needs the wave number integration for the inverse transform. This is performed by the Gauss quadrature and by the modified Clenshaw-Cirtis method. The time domain analysis used the Cgniad-de Hoop method for the analytical solution for a full plane.
Group pile foundations are constructed on soft soils to support superstructures. The present analysis took deliberate consideration for the pile soil pile interaction. The … More substructure method is used to advantage, splitting the soil and piles. The soil analysis is performed by use of the thin layer method. The pile analysis is made from the mass discrete system and the mass distributed system. The investigation is focused the pile head impedance function. The simulation is carried out for a single pile loading test. The investigation for rigid buried foundation is also executed.
The soil in strong ground motion attains high strains, indicating heavily nonlinear behavior with drift of the base line for the nonperiodic nature of seismic input. Assuming certain stress-strain relationship, response computation are made for the 1-dimensional and the 2-dimensional models by the direct step-by-step integration scheme and the equivalent method. The results are compared for the time histories and the response spectra. The difference of modeling and the characteristic of nonlinearity are clarified.
Those findings and results are effectively introduced for the analysis of extended structures. Less
