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 ...
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 ...
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 ...
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. ...
Implementation of a simplified method in design of hysteretic dampers for isolated highway bridges
(2017)
Abstract: Using seismic isolation systems for highway bridges modifies the structure’s principal vibration modes, effectively reducing the seismic base shear conveyed from the superstructure to the substructure. However, ...
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 ...
