Dynamic Responses of Underground Structures to Incident P, SV and Rayleigh Waves

investigation of dynamic responses of floating structures such as a barge under sea waves

determining the responses of floating structures at sea are the most important concerns in shipbuilding industry. in physical and dynamical principles a ship can be analyzed as a free elastic beam floating in sea without any supports. the analysis of corresponding dynamic equations are difficult and time- consuming, thus investigation on the behavior of floating structures can be done numerical...

seismic analysis of rectangular alluvial valleys subjected to incident sv waves by using the spectral finite element method

in this paper, an advanced formulation of the spectral finite element method (sfem) is presented and applied in order to carry out site response analysis of 2d topographic structures subjected to vertically propagating incident in-plane waves in time-domain. the accuracy, efficiency and applicability of the formulation are demonstrated by solving some wave scattering examples. a numerical param...

Inversion of QS of Deep Sediments from Surface-to-Borehole Spectral Ratios Considering Obliquely Incident SH and SV Waves

Previous studies (e.g., Satoh et al., 1995a) on inversion of quality factor for S waves, QS, of sediments using surface-to-borehole spectral ratios of seismograms, are mostly based on one-dimensional wave propagation of vertically incident SH waves. In this study a method is proposed for inverting frequency-dependent QS, S-wave velocity VS, P-wave velocity VP and incidence angle by considering ...
