   <dc:description>[ANGLÈS] In this thesis, a non linear analysis model of D regions is implemented based on&#xd;
the finite element method, which consider stage construction. In each stage, new&#xd;
elements and materials can be incorporated or removed; therefore, the model is&#xd;
suitable to account for strengthening and retrofitting. The model is based on&#xd;
modifications of previous version of a non linear model SATLAB, developed in the&#xd;
Department of Construction Engineering, and graphical user interface is developed.&#xd;
The model has also been improved to account for stage construction phases and&#xd;
anchorage failure of reinforcement has been considered in a simplified way. The&#xd;
model is validated after a series of experimental studies on D regions, available from&#xd;
the literature. Furthermore, tests on enlargements of pile‐caps are simulated; these&#xd;
tests will be conducted in the short‐term in the Structural Technology Laboratory of&#xd;
the UPC. Finally, the main conclusions of this research and recommendations are&#xd;
presented.</dc:description>
   <dc:description>[CASTELLÀ] En esta tesina se desarrolla e implementa un modelo de análisis no lineal para&#xd;
regiones D bidimensionales, mediante el método de los elementos finitos, que&#xd;
considera construcción por fases. En cada fase se pueden añadir o eliminar elementos,&#xd;
por lo que el modelo permite el estudio de los procesos de reparación y refuerzo. Para&#xd;
ello, se parte del modelo de análisis no lineal SATLAB, se desarrolla una interfaz gráfica&#xd;
y se implemente el análisis por etapas. La posible rotura por anclaje de las armaduras&#xd;
se ha considerado mediante un procedimiento simplificado. El modelo se valida&#xd;
mediante diferentes resultados experimentales de regiones D disponibles en la&#xd;
literatura. Posteriormente, se simulan una futura campaña experimental sobre&#xd;
encepados de pilotes recrecidos a realizarse a mediano plazo en el Laboratorio de&#xd;
Tecnología de Estructuras de la UPC. Finalmente, se ofrecen las principales&#xd;
conclusiones del estudio realizado.</dc:description>
