Texto completoThe last decades have seen the emergence of non-standard architectural shapes. Designers find often themselves helpless with the geometrical complexity of these objects. Furthermore, the available tools dissociate shape and structural behaviour, which adds another complication. This dissertation takes the point of view based on invariance under geometrical transformations, and studies several strategies for fabrication-aware shape modelling. Three technological constraints have been identified and correspond to three independent contributions of this thesis.The repetition of nodes is studied via transformations by parallelism. They are used to generalise surfaces of revolution. A special parametrisation of moulding surfaces is found with this method. The resulting structure has a high node congruence.Cyclidic nets are then used to model shapes parametrised by their lines of curvature. This guarantees meshing by planar panels and torsion-free beam layout. The contribution of this dissertation is the implementation of several improvements, like doubly-curved creases, a hole-filling strategy that allows the extension of cyclidic nets to complex topologies, and the generation of a generalisation of canal surfaces from two rail curves and one profile curves.Finally, an innovative method inspired by descriptive geometry is proposed to generate doubly-curved shapes covered with planar facets. The method, called marionette technique, reduces the problem to a linear problem, which can be solved in real-time. A comparative study shows that this technique can be used to parametrise shape optimisation of shell structures without loss of performance compared to usual modelling technique. The handling of fabrication constraints in shape optimisation opens new possibilities for its practical application, like gridshells or plated shell structures. The relevance of those solutions is demonstrated through multiple case-studies

Texto completoPreviously proposed computational methods for designing lightweight structures focused either on finding an equilibrium shape, or are restricted to fairly small design applications. In this work, we aim to develop a general, robust, and easy-to-use method that can handle many design parameters efficiently. These considerations have led to truss layout optimization, whose goal is to find the best material distribution within a given design domain discretized by a grid of nodal points and connected by tentative bars.
This general approach is well established for topology optimization where structural component sizes and system connectivity are simultaneously optimized. The range of applications covers limit analysis and identification of failure mechanisms in soils and masonries. However, to fully realize the potential of truss layout optimization for the design of lightweight structures, the consideration of geometrical variables is necessary.
The resulting truss geometry and topology optimization problem raises several fundamental and computational challenges. Our strategy to address the problem combines mathematical programming and structural mechanics: the structural properties of the optimal solution are used for devising the novel formulation. To avoid singularities arising in optimal configurations, the present approach disaggregates the equilibrium equations and fully integrates their basic elements within the optimization formulation. The resulting tool incorporates elastic and plastic design, stress and displacements constraints, as well as self-weight and multiple loading.
Besides, the inherent slenderness of lightweight structures requires the study of stability issues. As a remedy, we develop a conceptually simple but efficient method to include local and nodal stability constraints in the formulation. Several numerical examples illustrate the impact of stability considerations on the optimal design.
Finally, the investigation on realistic design problems confirms the practical applicability of the proposed method. It is shown how we can generate a range of optimal designs by varying design settings. In that regard, the computational design method mostly requires the designer a good knowledge of structural design to provide the initial guess.

Texto completoEste trabalho apresenta como objetivo principal avaliar o desempenho de blocos cerâmicos estruturais de 11,5 (Bloco A) e 14 (Bloco B) centímetros de largura, através de ensaios de blocos, prismas e pequenas paredes, utilizando dois traços de argamassa designados pela Norma Britânica, confeccionados em laboratório. O programa experimental compreendeu ensaios de compressão axial simples das unidades, prismas de três fiadas sobrepostas e pequenas paredes de dois blocos por quatro fiadas de altura. Durante os ensaios de prismas e pequenas paredes foram medidas suas deformações e, posteriormente, obtidos os módulos de elasticidade dos elementos. Com base na análise dos resultados, é possível concluir que o bloco com 11,5 centímetros de largura apresenta capacidade de absorver esforços equivalente ao bloco tradicional, podendo ser empregado com segurança. Foi possível verificar valores próximos de resistência à compressão para os corposde- prova ensaiados utilizando os dois tipos de blocos, estabelecendo comparações entre prismas e pequenas paredes com um mesmo traço de argamassa. Foi realizada a análise estatística do experimento, para verificar a comparação entre os dois blocos, onde foi observada a igualdade entre as resistências à compressão média para os ensaios de blocos e prismas com os dois tipos de argamassa, no entanto nos ensaios com pequenas paredes foi observada diferença entre as resistências médias obtidas com os dois tipos de blocos.

Texto completoThis thesis focuses on the structure and kinematics of the south-eastern Zagros Mountains (Iran) and the transitional structures with the adjacent Makran accretionary prism, known as the Bandar Abbas syntaxis. The structural style, as evidenced by a field-based structural study, is strongly controlled by changing mechanical stratigraphy and therefore paleogeographic conditions from one side to the other of the syntaxis. Restoration of the first complete balanced cross-section through the south-eastern Zagros fold-thrust belt shows that the external part of the orogen (a) underwent two main phases of deformation, i. E. A thin-skinned phase of deformation followed and partly overprinted by a thick-skinned phase, and (b) absorbed at least 45 km of shortening since middle Miocene times. The presence of an exceptionally thick layer of salt at the base of the cover allowed the development of huge detachment anticlines. Field examples from our study area and seismic profiles from Central Zagros allow us to discuss the still poorly understood kinematics of these folds as well as examine the various factors controlling the style of folding, essentially salt mobility, multiple decollement levels and late basement faulting. Finally, geophysical modelling of the deep lithospheric structure of Zagros brings new insight on the fundamental factors controlling the recent orogenic kinematics. In particular, a previously undocumented thinning of the lithosphere beneath Zagros could be attributed to recent slab break-off and is thought to have controlled the recent switch from thin-skinned to thick-skinned tectonics

Texto completoA systematic study of trends in band gap and lattice energies for bare zinc oxide nanoparticles were performed by means of quantum chemical density functional theory (DFT) calculations and density of states (DOS) calculations. The geometry of the optimized structures and the appearance of their frontier orbitals were also studied. The particles studied varied in sizes from (ZnO)6 up to (ZnO)192.The functionalization of bare and hydroxylated ZnO surfaces with MPTMS was studied with emphasis on the adsorption energies for adsorption to different surfaces and the effects on the band gap for such adsorptions.
