This paper presents the preliminary results of an extensive parametric study on seismic response of two-dimensional semi-sine shaped hills to vertically propagating incident P- and SV-waves. Clear perspectives of the induced diffraction and amplification patterns are given by investigation of time-domain and frequency-domain responses. It is shown that site geometry, wave characteristics , and ...

Seismic image and velocity models were obtained from a newly conducted seismic survey around the Integrated Ocean Drilling Program (IODP) Japan Trench Fast Drilling Project (JFAST) drill site in the Japan Trench. Pre-stack depth migration (PSDM) analysis was applied to the multichannel seismic reflection data to produce an accurate depth seismic profile together with a P wave velocity model alo...

With recent changes to the National Building Code of Canada (NBCC) in 2005 there has been an increasing demand for site classification based on dynamic shear wave velocity measurements of soil and rock. There are three seismic methods typically used for the NBCC seismic site classification; multichannel analysis of surface waves, vertical seismic profiling, and crosshole seismic testing. Typica...

The aim of the present paper is to evaluate the influence of the Soil- Foundation- Structure Interaction (SFSI) effects on the component demand modifier factor of concrete gravity beams based on ASCE 41-06 standard. To this end, the beam on the nonlinear Winkler foundation approach is employed which is a simple and efficient method. At first, four sets of 3-, 6-, 10- and 15-storey concrete mome...

This article presents a system identification analysis of a soil-structure interaction model with coupled horizontal and rocking response based on a combination of Fourier analysis, wave travel-time analysis, and a relationship between fixedbase, rigid-body, and system frequencies. The study provides insight into the coupling of the structural and soil vibrations useful for interpretation of se...

Dynamic response records of pile performance during earthquakes are limited mainly due to the challenges recording seismic soil–pile response. This limitation has led an inadequacy in providing a standardized basis for calibration and validation available analytical numerical methods developed superstructure interaction problems. To bridge this gap, series simulations scaled, shaking table test...

Aseismic design of gravity wall still is a more difficult issue. The reason stems from the complexity of the problem which requires skills in soil mechanics, foundation engineering, soil-structure interaction along with knowledge of structure dynamics. Designing seismic gravity retaining structures deals with both kinematic interaction and inertial interaction but almost seismic building code n...

The effect of local soil characteristics on the propagation earthquake waves has been commonly studied by researchers. However, validity results obtained these studies is limited only to relevant conditions. main purpose this study examine conditions seismic in Istanbul. In regard, information belonging different districts Istanbul compiled. site response analysis was simulated using a time-dom...

Abstract Ground motion selection is one of the most important phases in derivation fragility curves through non-linear dynamic analyses. In this context, an easy-to-use software, namely S&M—Select & Match, has been adopted for and spectral matching recorded ground motions approaching a target response spectrum broad period range. paper, after brief description key features S&M tool,...
