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 ...
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 ...
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 ...
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, ...
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 ...
