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. ...
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 ...
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 ...
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 ...
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 ...
Comparison of the statistical and information theory measures: application to automatic musical genre classification
(2007)
Abstract:
Recently considerable research has been conducted to retrieve pertinent parameters and adequate models for automatic music genre classification using different databases. Many of previous works are derived from ...
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. ...
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 ...
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 ...
