Site-City Interaction through Modifications of Site Effects
Jean-François Semblat, Marc Kham, Philippe Guéguen +2
The analysis of seismic site effects generally disregards the influence of surface structures on the free field motion in densely urbanized areas. This paper aims at investigating…
Seismic Site Effects for Shallow and Deep Alluvial Basins: In-Depth Motion and Focusing Effect
Jean-François Semblat, Patrick Dangla, Marc Kham +1
The main purpose of the paper is the analysis of seismic site effects in various alluvial basins. The analysis is performed considering a numerical approach (Boundary Element Metho…
Nonlinear viscoelastic wave propagation: an extension of Nearly Constant Attenuation (NCQ) models
Nicolas Delépine, Luca Lenti, Guy Bonnet +1
Hysteretic damping is often modeled by means of linear viscoelastic approaches such as "nearly constant Attenuation (NCQ)" models. These models do not take into account nonlinear e…
Numerical analysis of seismic wave amplification in Nice (France) and comparisons with experiments
Jean-François Semblat, Anne-Marie Duval, Patrick Dangla
The analysis of site effects is very important since the amplification of seismic motion in some specific areas can be very strong. In this paper, the site considered is located in…
Wave propagation through soils in centrifuge testing
J. F. Semblat, M. P. Luong
Wave propagation phenomena in soils can be experimentally simulated using centrifuge scale models. An original excitation device (drop-ball arrangement) is proposed to generate sho…
Rheological Interpretation of Rayleigh Damping
Jean-François Semblat
Damping is defined through various terms such as energy loss per cycle (for cyclic tests), logarithmic decrement (for vibration tests), complex modulus, rise-time or spectrum ratio…
