Su uso est\u00e1 cada vez m\u00e1s extendido debido a su ligereza y sencillez, lo cual otorga a \u00e9stas un atractivo especial como soluci\u00f3n arquitect\u00f3nica tanto a nivel est\u00e9tico como funcional. La combinaci\u00f3n de telas tensadas con otros materiales como el acero, la madera laminada, el hormig\u00f3n o el vidrio, permite crear formas complejas y sofisticadas. A pesar de todo, el dise\u00f1o y construcci\u00f3n de este tipo de estructuras sigue estando limitado a unos pocos profesionales y fabricantes debido al gran n\u00famero de t\u00e9cnicas que combinan. A ra\u00edz de esta problem\u00e1tica se plantean posibles soluciones que podr\u00edan facilitar el uso de este tipo de estructuras o bien acercar-lo a un mayor n\u00famero de profesionales. El principal problema con que se encuentra el dise\u00f1ador consiste en la generaci\u00f3n de la forma de la tela, la cual depende de la tensi\u00f3n a la que est\u00e1 sometida. Existen aplicaciones que permiten obtener dichas formas de equilibrio pero, la mayor\u00eda de ellas, son complicadas de manejar y se centran en la fase de an\u00e1lisis del modelo, siendo la interacci\u00f3n con el usuario muy deficiente. Por este motivo es necesario intervenir en la fase inicial del dise\u00f1o de estructuras tensadas, de modo que el dise\u00f1ador pueda plantear f\u00e1cilmente diferentes alternativas de dise\u00f1o de manera r\u00e1pida y eficaz. La presente tesis pretende cubrir esta necesidad mediante la introducci\u00f3n de t\u00e9cnicas computacionales que faciliten la generaci\u00f3n y manipulaci\u00f3n de este tipo de formas complejas de manera \u00e1gil y sencilla. Se propone un m\u00e9todo que combina t\u00e9cnicas estructurales con t\u00e9cnicas basadas en el ajuste de superficies param\u00e9tricas para la representaci\u00f3n de las mismas en tiempo real.   tensile structures are used for many different purposes, as ornamental elements, as lightweight structures to cover medium size \u00e1reas or as wide span enclosures to cover big spaces as stadium roofs. Due to its lightweight and simplicity, the use of these kinds of structures is increasing, as they are appropriate architecture solutions that cover aesthetic and functionally aspects. The combination of coated woven fabric with other materials as steel, wood, concrete or glass offers the possibil ity to the designer to cr\u00e9ate complex and sophisticated shapes. Unfortunately, the design and construcci\u00f3n of this kind of structures is still limited to a small number of people and manufacturers, due to the large number of techniques used. For this reason, some solutions are described which would facilitate the use of this kind of structures, or bring them to a large number of people. The main handicap for the tensile structure designers consists on finding the equilibrium shape of a membrane, which depend on its given pre-stress. Many applications can be used to obtain these equilibrium shapes, but most of them are difficult to control or are more focused on the ana\u00edysis stage, being the interface with the user quite deficient. Due to this, it is clearly necessary to act in the initial stages of the tensile structures design process, to offer the designer the opportunity of cr\u00e9ate differ-ent design alternatives in an easy and effective way. This dissertation introduces some computational techniques to gen\u00e9rate and manip\u00falate these kinds of complex shapes easily and quickly. A method is proposed which combines structural and surface fitting techniques to represent efficiently these kinds of shapes in real time.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis
