Experimental study of dynamic bending stiffness of ACSR overhead conductors
(2015)
Abstract : Aeolian vibrations of transmission line conductors may cause fretting fatigue failure at or near the location of clamped devices. At these locations, the bending stiffness variation of the conductor has a large ...
Modeling multilayered wire strands, a strategy based on 3D finite element beam-to-beam contacts - Part II: Application to wind-induced vibration and fatigue analysis of overhead conductors
(2017)
Abstract: Wind-induced loads cause electrical transmission line fatigue. Evaluation procedures consider descriptors such as deflection amplitude (Yb) and far-field vibration (fymax), which cannot relate endurance limits ...
Effect of geometric parameters on the behavior of bolted GFRP pultruded plates
(2016)
Abstract : This paper presents the effect of geometric parameters on the behavior of bolted GFRP pultruded plates for civil engineering applications. After a literature review, results of an experimental analysis investigating ...
Strengthening of the net section of steel elements under tensile loads with bonded CFRP strips
(2014)
Abstract : The use of CFRP is increasingly common as a solution for the strengthening of structures, but the majority of research and applications have focused on the retrofit of concrete structures. The application of ...
Experimental investigation of multi-material aluminum-to-steel and GFRP-to-steel bonded and bolted/bonded connections
(2016)
Abstract : Through an experimental study, this paper describes the behavior of single-lap bonded, bolted and bolted/bonded connections for configurations with minimum geometric parameters proposed in design references. Two ...
Effect of geometrical parameters of aluminum-to-steel bolted connections
(2015)
Abstract : Through experimental and numerical studies, this research work aims to provide directions on the optimal geometric configuration for single-lap and double-lap bolted connection between aluminum alloy 6061-T6 and ...
Failure analysis of transmission line steel lattice towers subjected to extreme loading
Other titre : Building tomorrow’s society / Bâtir la société de demain
(2018)
Abstract: Lattice towers are extensively used in overhead transmission lines, owing primarily to their lightness and cost-effectiveness. The modeling of such structures is usually laborious due to various complex factors ...
Numerical analysis of ACSR conductor-clamp systems undergoing wind-induced cyclic loads
(2018)
Abstract—Submitted to wind induced vibrations, overhead
conductors are vulnerable to fatigue damage, especially at
restraining fixtures such as the suspension clamp. This paper
proposes an efficient finite element ...
Détermination de la plus-value de la télédétection pour le suivi des niveaux d’eau et du bilan hydrique : Application au réservoir Eastmain-1
(Université de Sherbrooke, 2020)
Le nouvel altimètre radar SWOT va permettre de produire des cartographies à haute résolution des niveaux des eaux de surface à partir de 2021. L’objectif du projet est de déterminer en quoi ce satellite à haute-résolution ...
Time-domain analysis of solar concentrator structure under gust wind
(2017)
Abstract: Accurate evaluation of wind load effects on solar structures is important for optimizing their design. Gust wind and its dynamic effect may be significant for this type of structure, however while time-domain ...
