The development of efficient algorithms to understand implosion dynamics presents a number of challenges. The foremost challenge is to efficiently represent the coupled compressible fluid dynamics of internal air and ...
This work covers a contribution to two most interesting research elds in aerodynamics, the fi nite element analysis of high-speed compressible flows (Part I) and aerodynamic shape optimization (Part II). The fi rst part ...
Rockfill dams are nowadays often preferred over concrete dams because of their economic advantages, their flexible design and thank to the great advance achieved in geosciences and geomechanics. Unfortunately their behavior ...
The world of computing simulation has experienced great progresses in recent years and requires more exigent multidisciplinary challenges to satisfy the new upcoming demands. Increasing the importance of solving ...
El estudio de la mecánica computacional de fallo ha ganado creciente popularidad en los últimos años. Modelizar el comportamiento poscrítico de estructuras puede alcanzar un grado elevado de complejidad, debido a la ...
Modelling of granular materials, soils and rocks has been a challenging topic of investigation for decades. Classical continuum mechanics has been used to idealize soils and rocks, and numerical solution techniques such ...
A significant number of buildings are supported by load-bearing masonry walls. The preservation of these worldwide used structures is a sustainable alternative. However, there is little research about the structural response ...
Cold-formed thin-walled steel sections are frequently used in pallet rack structures. This type of cross-sections are normally used as a columns and contains perforations uniformly distributed enabling the connection between ...
El contenido de la tesis que se presenta se ha organizado de la manera siguiente:<br/><br/>A lo largo del capítulo 2 se describen los aspectos generales del estado del arte del análisis de sensibilidad, centrándose en las ...
In the situation to make decisions about which risk mitigation measures -RMM- to implement and the performance level required, arises the need for a quantitative analysis of benefits that may be obtained as well as the ...
Este trabajo tiene por objetivo desarrollar una estrategia orientada a resolver de forma computacional el equilibrio estático de las obras pétreas formadas por elementos unidimensionales empleando la analogía clásica de ...
Los daños por terremotos en edificios y sistemas esenciales han motivado la definición de estándares de comportamiento de estas instalaciones, buscando reducir las pérdidas económicas y la pérdida de funcionalidad. Varias ...
El continuo deterioro y/o daños causados en las estructuras de hormigón durante su vida útil, son fenómenos inevitables que conlleva el paso del tiempo y viene a ser un problema importante que ha conducido al desarrollo ...
The present work focuses on the formulation of a Continuum Damage Mechanics model for nonlinear analysis of masonry structural elements. The material is studied at the macro-level, i.e. it is modelled as a homogeneous ...
Este trabajo presenta una reformulación de la metodología de discontinuidades fuertes de continuo para la simulación numérica del fallo material de estructuras.<br/>Los objetivos buscados han sido mejorar la robustez de ...
El progresivo incremento de la altura de los Edificios de Gran Altura (EGA) ha aumentado las consecuencias reales y potenciales cuando irrumpen en ellos incendios naturales. A la vista de dichas pérdidas, el objeto principal ...
The present project is aimed to analyze the steel structure from an evolutionary point of view. The study¿s context has been the 20th century on the Catalan capital city in order to see how the historical, normative and ...
The objective of this thesis is to develop and evaluate a methodology for the solution of the Navier-Stokes equations for Bingham Herschel-Bulkley viscoplastic fluids using stabilized mixed velocity/pressure finite elements. ...
El fallo resistente de las losas mixtas se produce generalmente por el deslizamiento longitudinal entre la chapa nervada de acero y el hormigón. La dificultad de diseño de chapas para losas mixtas reside en asegurar su ...
The natural hazard risk is a contingent liability and, thus, a sovereign risk for national governments and, therefore, it is important to assess properly the potential losses in order to design suitable policies and ...
