Abstract In order to quantitatively evaluate the one-dimensional site seismic response analysis methods, this article selected 2418 ground motion records of Japan KiK-net strong-motion seismograph network and groups acceleration spectra calculated by DEEPSOIL, SHAKE2000, SOILQUAKE SOILRESPONSE, then` used dynamic time warping (DTW) algorithm calculate DTW distance between measured spectrum spec...

in this paper, pile behavior embedded in layered soil deposits subjected to seismic loadings is analyzed using a nonlinear fiber element for simulation of soil – pile interactions. in the created model, both pile and surrounding soil are modeled using fiber elements in a practical beam on nonlinear winkler foundation (bnwf) concept. herein, the features of drain–3dx finite element software are ...

This paper employs one-dimensional numerical ground response analysis models to investigate seismic response of shallow cohesive and non-cohesive soil deposits on vertical propagation of horizontal shear waves. Soil response is modelled by traditional equivalent-linear (EL) frequency-domain analysis using DEEPSOIL software and nonlinear (NL) time-domain analysis using OPENSEES software. The ana...

The paper describes an integrated approach to seismic hazard assessment, which was applied for the Taiwan region. First, the theoretical seismic catalogue (2001-2050) for the Taiwan region had been calculated using the 4D-model (location, depth, time) for dynamic deformation of the Earth’ crust and 5D-model (location, depth, time, magnitude) for seismic process. The models were developed on the...

iran is an active seismic region. earthquake damage is commonly controlled by three interacting factors including source and path characteristics, local geological and geotechnical conditions and type of the structures. obviously, all of this would require analysis and presentation of a large amount of geological, seismological and geotechnical data. in this paper, nonlinear geotechnical seismi...

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...

Ground response analyses are mostly used for the development of design response spectra in the modern earthquake engineering. After 1999 Marmara Earthquake, the damages were mostly related with unavailable soil conditions and this unavailability were analysed according to liquefaction analysis. The other analyses which cover the dynamic soil properties were not studied in detail. In this study,...

A noticeable feature of many earthquake-prone cities such as Kobe (Japan), Izmit (Turkey), Nice (France), Mexico City, Los Angeles etc., is that they are partially or wholly built on soft soil. A straightforward 1D analysis (which takes no account of the presence of the buildings) shows that the soft layer increases the seismic vulnerability of the city in that it is responsible for amplificati...

Studies of earthquakes over the last 50 years and the examination of dynamic soil behavior reveal that soil behavior is highly nonlinear and hysteretic even at small strains. Non-linear behavior of soils during a seismic event has a predominant role in current site response analysis. The pioneering work of H. B. Seed and I. M. Idriss during the late 1960’s introduced modern site response analys...

Abstract In this paper the site categorization criteria and corresponding amplification factors proposed in 2021 draft of Part 1 Eurocode 8 (2021-draft, CEN/TC250/SC8 Working Draft N1017) are first introduced compared with current version 8, as well from recent empirical ground motion prediction equations. Afterwards, these values checked by two approaches. First, a wide dataset strong records ...
