The possibility is here explored to use an ‘equivalent’ homogeneous configuration simulate 1D seismic response of heterogeneous engineering-geological bodies when relatively weak impedance contrasts internal the (it was assumed a shear wave velocity variation between alternating layers equal 150 m/s) only exist above bedrock. This equivalent obtained by considering Vs value harmonic average act...

In the context of seismic risk, studying characteristics urban soils and built environment means adopting a holistic vision city, taking step forward compared to current microzonation approach. Based on this principle, CLARA WebGIS aims collect, organize, disseminate available information buildings in area Matera. The geodatabase is populated with (i) 488 downloadable geological, geotechnical, ...

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...

The Yogyakarta earthquake in 2006 caused damage several areas, especially the area of Klaten Regency. As a result, many infrastructures, houses, health facilities and casualties have been damaged. research was conducted with target knowing level earth's hazard by microzoning soil vulnerability areas Bayat District, Klaten, Central Java. This study used microseismic method HVSR (Horizontal to Ve...

The use of the shear wave velocity data as a field index for evaluating the liquefaction potential of sands is receiving increased attention because both shear wave velocity and liquefaction resistance are similarly influenced by many of the same factors such as void ratio, state of stress, stress history and geologic age. In this paper, the potential of support vector machines (SVM) based clas...
