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 ...
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 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 ...
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 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 ...
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 ...
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 ...
Effect of the design resistance of structures on the extent of transmission line cascading failures
Other titre : Building on our growth opportunities = Miser sur nos apportunités de croisssance
(2015)
Abstract: Transmission line structures may suffer catastrophic losses when cascading failures occur. These events are caused by dynamic loads often related to the sudden ruin of conductors or other mechanical equipment. ...
Influence of damping and force hypotheses for evaluating ductility demand of structures subjected to time history wind loading
(2017)
Abstract: Current wind design procedures require that structural behavior remains elastic under wind loading corresponding to a specific return period unlike seismic codes that set some specifications to account for the ...
