Aerodinámica, dinámica y aeroelasticidad de estructuras
Diagrama de temas
-
El curso brinda los fundamentos y técnicas utilizadas en ingeniería del viento con énfasis en la acción del viento y su efecto sobre estructuras. Los estudiantes adquieren los fundamentos para calcular la respuesta de distintos tipos de estructuras a la acción del viento, y la habilidad para reconocer las estructuras sensibles a la acción del viento, la respuesta dinámica esperada y fenómenos de inestabilidad aeroelástica.
A lo largo del curso se tendrán clases teóricas y otras en las que se aplicarán técnicas numéricas, analíticas y experimentales al estudio de estructuras reales. Como parte del curso se ofrecerá también cuatro seminarios, abiertos a todo público, que ilustran aspectos generales y temas de investigación actuales en ingeniería del viento.
El curso será ofrecido en forma gratuita a alumnos inscriptos a maestrías o doctorados en Facultad de Ingeniería y tendrá un costo de $U 5.000 para profesionales que deseen realizarlo como curso de actualización.
Las inscripciones deberán ser tramitadas en bedelía, aunque todavía no es posible hacerlo. Cuando sea posible se avisará en este espacio.
El curso será dictado en inglés, por el Prof. Giovanni Solari de la Universidad de Génova en Italia. Los horarios, el lugar y demás información se encuentra en los documentos a continuación.

Para la inscripción al curso el trámite debe realizarse en bedelía, pero por ahora no es posible. Muy probablemente la inscripción deba tramitarse después del inicio de las clases. Por lo tanto se recomienda asistir a la primera clase, la cual comienza con el primer seminario el lunes 30 de noviembre a las 17 horas en el salón de posgrados del IMFIA.
Para utilizar el foro de consultas y/o recibir mensajes de los docentes se recomienda la inscripción a esta página eva, que es de inscripción libre para quienes poseen usuario eva. Los alumnos y docentes de facultad ya pueden hacerlo pues ya lo poseen. Las demás personas que no posean usuario eva pueden hacerlo también, pero es necesario que envíen nombre completo, documento de identidad y email a la dirección acanelas@fing.edu.uy para solicitarles un usuario eva.

Se recomienda fuertemente la lectura de las notas de dinámica estructural a quienes deseen asistir y no tengan conocimientos de dinámica estructural.

Por otra parte, el Prof. Solari brindará algunos seminarios que serán parte del curso de posgrado pero que además estarán abiertos al público.
Los seminarios son abiertos pero requieren confirmación de asistencia de aquellos interesados estén o no inscriptos al curso. La asistencia se confirmará a través del Foro de consultas de esta página o al email acanelas@fing.edu.uy.
Los seminarios se describen a continuación:

Abstract:
Few natural phenomena have been the object of speculation, observations, experiences and research as abundant as those carried on the wind. This is mostly due to the rare property of dualism owned by the wind: the wind is evil when it destroys buildings and anthropogenic areas, producing more fatalities and damages than any other natural event; when it whips men, houses and settlements with either too cold or hot air; when it makes uncomfortable the use of urban spaces; when it destroys cultures and subjects transports to serious risks; when it erodes the soil to the point to make desert whole lands; when it drifts snow, burying buildings and roads; when it is a tool for air pollution and for the aggression to monumental heritage. On the other hand, the wind is good because, as the engine of atmospheric and ocean motions, the life on Earth would not exist without it. The wind is good when it powers windmills and wind turbines, producing clean renewable energy; when it favours the circulation of fresh air inside buildings or along the arteries of the urban fabric; when it offers breath to the populations that live in deserts or in lands too dried by the sun; when it disperses the emissions of pollutant sources away from populated areas and heat urban islands.
Wind Engineering is best defined as the rational treatment of interactions between wind in the atmospheric boundary layer and man and his works on the surface of Earth. The International Association for Wind Engineering promotes international co-operation among scientists, engineers and other professionals for the advancement of knowledge in the broad field of wind engineering. This presentation provides an overview of the many topics embraced by wind engineering, pointing out the most consolidated aspects of this discipline and the new emerging fields.

Abstract:
From the beginning of the XX century, research in aerodynamics is a cornerstone in the design of the shape of planes, trains, automobiles, sailboats, kites, windmills and other objects that interact with fluids. In this framework, buildings are a clear anomaly: their shape is generally a prerogative of architectural design, while the structural engineer is often limited to take them into account as an element needed to evaluate the actions and effects induced by the wind.
Based on this premise, the engineer then develops a wide range of tools aimed at counteracting aerodynamic actions. At the beginning of the XX century, criteria are developed for the selection of material and robust static conceptions. At the middle of the century the engineer starts to exploit the potential of computers and wind tunnels to pursue rational projects. Later he gives rise to a broad range of devices to dissipate energy through forms of control initially passive, then also active.
The choice of the building shape on the basis of aerodynamic conceptions at the interface between architecture and engineering explodes at the beginning of the new millennium, bringing to light an unlimited number of tall buildings inspired by rigorous optimization strategies. By virtue of these principles, the height and slenderness of buildings undergo explosive growth witnessed by buildings currently under construction and by projects waiting to be realized.

Abstract:
This seminar provides a synthesis and the main results of the research carried out at the University of Genoa on thunderstorm monitoring, modelling, response and loading of structures.
Thunderstorm detection is carried out by the monitoring network realized for the European projects “Wind and Ports” and “Wind, Ports and Sea” in the Northern Tyrrhenian area. The measured data are transferred to a central server that stores the raw data and their statistical values into a central dataset. A procedure has been implemented to separate different intense wind events.
Each thunderstorm velocity record is decomposed into the sum of its slowly-varying mean part plus a residual fluctuation given by the product of its time-varying standard deviation by a random stationary standardised Gaussian signal. The main parameters of each record are collected and statistically analysed to establish a realistic parameterized thunderstorm model.
The structural response to thunderstorms is evaluated through an evolution of the response spectrum technique widely diffused in the seismic sector. This technique is first developed for single-degree of freedom systems subjected to perfectly coherent wind fields, then it is extended to multi-degree of freedom systems subjected to partially coherent wind fields.
The response spectrum technique is embedded into the independent wind loading technique. In place of the classical unique wind loading condition that joins different wind phenomena by mixed statistics, it gives rise to as many independent wind loading conditions as the wind phenomena that characterize the mixed climate, first of all synoptic and thunderstorm events.

Abstract:
The Endless Column by Constantin Brâncuşi is “the most radical sculpture in the history of classic modernism”, “the only one of modern times that can be compared with the great Egyptian, Greek and Renaissance monuments”. It “is not only an artistic masterpiece, but also an extraordinary feat of engineering”, the major example of cooperation between a sculptor and an engineer. The seminar illustrates the path that led the artist to the conception of the column, its planning and construction, the investigations on the preservation of the monument and its restoration, the aerodynamic tests in the wind tunnel, the modeling of the wind and the structure by which the aeroelastic instability, the dynamic response and the fatigue life were investigated. The conclusions discuss the column’s role in the panorama of the great works of modern engineering.
