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 ...
Substructuring strategy for pseudo-dynamic testing of steel lattice towers
Other titre : Growing with youth / Croître avec les jeunes
(2019)
Abstract: Lattice towers are the most commonly used structures in the field of overhead power transmission lines. In the design process of transmission lines, there are several methods for the evaluation of their capacity. ...
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 ...
Study on extraction parameters of flutter derivatives for the development of a time-domain formulation of self-excited forces
(2017)
Abstract: This paper addresses the evaluation of the dependence of bridge-deck flutter derivatives to the extraction parameters used in wind tunnel tests. The studied parameters are the model scale, model velocity and ...
Evaluation of phase-to-phase clearances of transmission line conductors under turbulent wind
(2017)
Abstract: "Wind loads govern the design of a large number of overhead transmission lines worldwide. The spatial and temporal variation of wind speed and the buffeting response of cables may induce swings not fully synchronized ...
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 ...
Full-scale measurement of the response of a CPV tracker structure prototype under wind load
(2017)
The response of concentrated photovoltaic (CPV) structures under wind loading has to be carefully predicted to optimize the design of these structures. Designers normally rely on wind tunnel tests and equivalent static ...
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. ...
