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 ...
Assessment of the effect of residual stresses on the mechanical behavior of steel lattice transmission towers
Other titre : Building tomorrow’s society / Bâtir la société de demain
(2018)
Abstract: Power transmission lines predominantly involve lattice towers, which are typically composed of steel angle members connected together by means of bolted joints. An effective design of such structures requires the ...
Resistance and failure modes of cold-formed lipped angle subjected to tensile load
Other titre : Building tomorrow’s society / Bâtir la société de demain
(2018)
Abstract: Cold-formed steel angles could be an advantageous alterative to hot rolled steel angle for the application of light-weight electrical transmission towers. However, standard design equations to evaluate the ...
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 ...
Prédiction des vibrations éoliennes d'un système conducteur-amortisseur avec une méthode temporelle non linéaire
(Université de Sherbrooke, 2013)
Les vibrations éoliennes sont la cause principale de bris de conducteurs en fatigue des lignes aériennes de transport d'énergie électrique. Ces vibrations sont dues à des détachements tourbillonnaires produits dans le ...
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 ...
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 ...
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 ...
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 ...
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 ...
