Abstract

Civil engineering constructions like pedestrian footbridges are structures increasingly slender, ambitious and complex in which the dynamic effects caused by the loads to which they are subjected (pedestrians) may induce service problems and / or significant or repetitive amplifications [...]

Abstract

International audience; The degradation of railway tracks can be observed through several measurement techniques. Recently, a method to diagnose the railway track using Fiber Bragg gratings (FBG) has been proposed. FBG are integrated inside the railway sleeper and is named a "Smart [...]

Abstract

International audience; Tramway traffic may produce vibrations propagating in soil, which implies vibration annoyance for people living or working in neighbouring buildings. Thus vibration is one of the most important consequences to be considered when planning new lines. Dynamic [...]

Abstract

"jats:p" The natural soil used in filling the embankment of the road communications is characterized by the following factors: humidity, porosity, toughness. For certain factor values that describe the soil state is distinguished a certain soil behavior under the influence of the [...]

Abstract

his paper proposes a new vibration-based structural health monitoring method for the identification of delamination defects in composite bulkheads used in small-length fiber-based ships. The core of this work is to find out if the variations of vibration energy can be efficiently [...]

Abstract

Noise transmitted by the sidewalls of buildings is essential to study the overall airborne sound insulation. For the determination of the lateral transmissions we must determine a parameter known as vibration reduction index. To obtain the value of the vibration reduction index to [...]

Abstract

International audience; This study deals with the dynamic and thermal behaviors of supercapacitors. Characterization is performed using the Electrochemical Impedance Spectroscopy (EIS) method to determine by experiment the supercapacitor's series resistance (ESR) and capacitance according [...]
