In seismic resistance design, the design seismic motion is usually defined by elastic response spectra to reflect the characteristic in frequency. Whilst, either the phase of a reference seismic record or random phase is used in generation of artificial wave. The influence of phase on structural response can not be properly defined, as it is often omitted for linear elastic responses. But for t...

The Seismic Research Centre, University of the West Indies operates a seismic network that performs suboptimally in detecting, locating, and correctly determining the magnitude of earthquakes due to a diverse constituion of seismometers and the utilization of a site selection process that approximates an educated guess. My work seeks to apply Self-Organizing Maps (SOM) to arrive at the optimal ...

the present study presents an algorithm that models uncertainties at the structural component level to estimate the performance reliability of rc structures. the method calculates the performance reliability using a systemic approach and incorporates the improved response surface method based on sampling blocks using the first-order reliability method and conditional reliability indices. the re...

Due to the introduction of Eurocode 8, the structural design for seismic and dynamic effects has become more significant in Hungary. This has emphasized the need for more effort to describe the behavior of structures under these conditions. Soil conditions have a significant effect on the response of structures by modifying the stiffness and damping of the soil-structural system and by modifyin...

In order to compare and analyze the seismic response characteristics of a safety-related nuclear structure on non-rock site in condition raft pile group foundations under unidirectional multidirectional motion input, large-scale shaking table test soil-nuclear system was carried out this paper. test, soil uniform silted clay, shear wave velocity 213 m/s. Considering similarity superstructure na...

Abstract Quantitative estimation of seismic risk over a region requires both an underlying probabilistic hazard model and means to characterise shallow site response large scale. The 2020 European Seismic Risk Model (ESRM20) builds on the Hazard (ESHM20), requiring additional information firstly parameterise local condition across all Europe, subsequently determine its influence prediction grou...
