Direct drilling method and the use of microtremor studies are among the most commonly used available methods utilized to estimate dynamic parameters for a site. One of the most important parameters is the dominant period of the site whose estimation plays a pivotal role in seismic hazard mitigation. The conventional models obtained are not capable of estimating the parameters that govern the se...

Presented here is an analysis of the effects of soil-foundation-structure interaction (SFSI) on seismic response of highway bridges. Of particular importance is the issue of input motions, their scaling and application to the SFS models. The analysis presented in this paper addresses the influence of inelastic behavior of both the soil and the structural components during seismic response evalu...

Probabilistic seismic hazard analysis is a technique for estimating the annual rate of exceedance of a specified ground motion at a site due to the known and suspected earthquake sources. A Monte-Carlo approach is utilized to estimate the seismic hazard at a site. This method uses numerous resampling of an earthquake catalog to construct synthetic catalogs to evaluate the ground motion hazard a...

Recent investigations have shown that the influences of Soil-Structure Interaction (SSI) may be detrimental to the seismic response of structure, and hence neglecting this phenomenon in analysis and design may lead to an un-conservative design. The objective of this paper is to quantify the effects of nonlinear soil-structure interaction on the seismic response of a low-rise special moment fram...

S U M M A R Y We systematically analyse non-linear effects and temporal changes of site response associated with medium-size earthquakes, using seismic data recorded by the Japanese Strong Motion Network KIK-Net. We apply a sliding-window spectral ratio technique to surface and borehole strong motion records at six sites, and stack results associated with different earthquakes that produce simi...

This paper presents the complete algorithm of site response analysis of nonhomogeneous topographic structures using transient two-dimensional boundary element method (BEM). Seismic behaviour of various topographic features including canyon, half plane, sedimentary filled valley and ridge sections, subjected to incident SV and P waves are analysed. The analysis shows the efficiency of the propos...

The KiK-net is a vertical array system, and seismic motions are recorded at the ground surface and in the borehole. With the peak acceleration of 24.5 m/s2 at AKTH04 (EW) and 38.7 m/s2 at IWTH25 (UD) during the Iwate–Miyagi Nairiku earthquake in 2008, the occurrence mechanism of large accelerations is investigated by the non-stationary Fourier spectra and the double integrated displacement prof...

Abstract This paper presents calculated ground motions for Merangin Kerinci in the Provinsi of Jambi Sumatera. The were using a probabilistic seismic hazard analysis. earthquake catalogue used analysis included all recorded earthquakes up to end July 2019, trimmed magnitude completeness. Uncertainty input parameters was considered logic tree, with branches including shallow crustal faults Great...

SUMMARY The within-site variability in site response is the randomness at a given from different earthquakes and treated as aleatory current seismic hazard/risk analyses. In this study, we investigate single-station linear K-NET KiK-net stations Japan using large number of earthquake recordings. We found that standard deviation horizontal-to-vertical Fourier spectral ratio individual sites, (HV...
