The aim of this paper is to investigate the ability of various site‐condition proxies (SCPs) to reduce ground‐motion aleatory variability and evaluate how SCPs capture nonlinearity site effects. The SCPs used here are time‐averaged shear‐wave velocity in the top 30 m (VS30), the topographical slope (slope), the fundamental resonance frequency (f0) and the depth beyond which Vs exceeds 800 m/s (...

The seismic risk assessment of existing urban areas provides important information for the process reduction in different phases planning and emergency management. Between large-scale approaches, a vulnerability index method is often used first screening buildings classification. However, this cannot fully predict effects specific action on buildings. This paper extends scale settlement properl...

This article presents equations for the estimation of vertical strong ground motions caused by shallow crustal earthquakes with magnitudes Mw ≥ 5 and distance to the surface projection of the fault less than 100 km. These equations were derived by weighted regression analysis, used to remove observed magnitude-dependent variance, on a set of 595 strong-motion records recorded in Europe and the ...

In order to grasp the nonlinear experimental errors of dynamic shear modulus ratio (DSMR) and damping (DR), as well current level resonant column testing, GZ-1 instrument was used study probability statistical indicators, basic laws, impact on peak acceleration DSMR DR silt under 8 typical strains. The results show that, firstly, different strains obey normal distributions. Secondly, there is n...
