The plane frame formed by precast elements have been increasingly used in structural systems of buildings throughout Brazil. These frames, as most of the precast structures deformable connections have a greater or lesser degree. The aim of this study is to analyze the structural behavior of portal frames composed of precast reinforced concrete taking into account the variation in the stiffness of the connections and the physical and geometric nonlinearity evaluated by approximate methods. The analysis of geometric nonlinearity was taken through the process P- and physical nonlinearity was checked by the Branson method. For the analysis of material and geometric nonlinearity simultaneously proposed a coupling of the two methods mentioned above. The proposed coupling was tested in a case study of a building with four floors, considering the loads recommended by NBR 6118 (ABNT, 2014) and evaluating the influence on the stiffness of two beam-column connection types. The results show an increase in the displaceability of the structure more deformable links analyzed five times at the most critical situation is compared with the evaluated frames with more rigid links. The structures analyzed taking into account the nonlinearities present in the internal structural strain variations of up to 162% compared with the linear analysis. Therefore it can be stated that the determination of the stiffness of the connections and the consideration of nonlinearities directly influenced the behavior of the efforts that will act in the structure, and therefore the structural analysis and design of the components of the same. / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Os pórticos planos formados por elementos pré-moldados vêm sendo cada vez mais utilizados em sistemas estruturais de edifícios em todo Brasil. Esses pórticos, como a maior parte das estruturas pré-moldadas, apresentam ligações deformáveis em maior ou menor grau. O objetivo geral deste trabalho é analisar o comportamento estrutural de pórticos planos formados por elementos pré-moldados de concreto armado levando em consideração a variação na rigidez das ligações e as não-linearidade física e geométrica avaliadas por métodos aproximados. A análise da não-linearidade geométrica foi feita através do processo P- e a não-linearidade física foi verificada através do método de Branson. Para a análise das não-linearidades física e geométrica de maneira simultânea foi proposto um acoplamento dos dois métodos citados anteriormente. O acoplamento proposto foi testado em um estudo de caso de um edifício com quatro pavimentos, considerando-se os carregamentos recomendados pelas normas brasileiras e avaliando-se a influência na rigidez de duas tipologias de ligação viga-pilar. Os resultados obtidos mostram um aumento na deslocabilidade da estrutura analisada com ligações mais deformáveis de cinco vezes na situação mais crítica se comparado com os pórticos avaliados com ligações mais rígidas . As estruturas analisadas levando em consideração as não-linearidades apresentaram variações nos esforços internos solicitantes de até 162% se comparadas com a análise linear. Portanto pode-se afirmar que a determinação da rigidez das ligações e a consideração das não-linearidades influem diretamente no comportamento dos esforços que irão atuar na estrutura e por consequência, na análise estrutural e dimensionamento dos elementos que compõem a mesma.

L'objectif de cette thèse est de modéliser les changements en chaîne historiques dans les théories phonologiques modernes. Martinet (1952, 1955, 1970) distingue deux principales catégories de changements en chaîne: les chaînes de propulsion et les chaînes de traction. Les chaînes de propulsion seront traitées dans la première partie de cette thèse (chapitres 2 et 3). Afin de modéliser les chaînes de propulsion, un modèle existant est utilisé: La théorie de préservation du contraste de Łubowicz (2003, 2012). Concernant la modélisation des chaînes de traction, qui sera principalement traitée dans la seconde partie de le thèse (chapitres 4 et 5), une nouvelle théorie sera proposée, basée sur les travaux phonétiques de De Boer (2001). Cette proposition est basée sur la notion des domaines piliers. Le chapitre 1 s'ouvre sur l'observation que ni les théories dérivationnelles orientées vers l'input – type SPE – ni les théories orientées vers l'output, comme la théorie de l'optimalité de Prince & Smolensky (TO) sont en mesure de formaliser les changements en chaîne. Dans les théories dérivationnelles, il est possible d'obtenir une bonne description des changements en chaîne. Cependant, afin de faire cela, nous devons briser les liens unissant les différentes étapes des changements en chaîne. Par conséquent, nous perdons l'interdépendance systémique entre les stades, ce qui est au cœur des changements en chaîne. Concernant la théorie de l'optimalité, sa structure stricte sur deux niveaux se révèle problématique dans le cas des changements en chaîne. Dans un changement en chaîne schématique comme /a/ → [e] > /e/ → [i], il est impossible pour la TO, dans la même analyse, de faire en sorte que [e] soit un candidat optimal et /e/ un candidat bloqué. Dans le chapitre 2, nous analysons et comparons plusieurs amendements à la théorie de l'optimalité proposés pour rendre compte des changements en chaîne. Beaucoup d'entre eux ne sont pas satisfaisants dans le cas des changements en chaîne car ils ne parviennent pas à modéliser la force systémique des changements en chaîne. La seule théorie qui semble accomplir cet objectif est la théorie de préservation du contraste (CPT) de Łubowicz. Cette théorie est basée sur les notions de contraste, préservation du contraste et elle évalue des scénarios au lieu de candidats individuels. La préservation du contraste est accomplie à travers la transformation du contraste. La notion de transformation du contraste signifie que les niveaux de contraste du système pré-changement sont préservés dans le système post-changement mais leur nature change. Une observation sur la CPT est que Łubowicz l'avait originellement conçue pour les changements en chaîne synchroniques. Dans le chapitre 2, nous démontrons que la CPT est en mesure de modéliser la force systémique qui donne aux changements en chaîne diachroniques leur cohérence. Ainsi, dans le chapitre 3, nous décidons de tester la validité de la CPT sur de véritables changements en chaîne historiques. Nous avançons deux études de cas sur deux changements en chaîne. Le premier, bien connu, est le changement en chaîne vocalique du Grand Changement Vocalique Anglais (English Great Vowel Shift). L'autre changement en chaîne est la Seconde Mutation Consonantique allemande (High German Consonant Shift). Nous démontrons que la CPT est en mesure de rendre compte de ces deux changements en chaîne. Au terme du chapitre 3, la CPT est testée sur une autre catégorie de changements en chaîne : les changements en chaîne observés dans l'acquisition de la langue maternelle. Le changement en chaîne étudié est s → θ → f. Ce changement en chaîne est différent des deux autres car il n'y a pas de nouveau niveau de contraste créé. Le dernier stade du changement en chaîne se conclut par une fusion. Encore une fois, la CPT peut rendre compte de ce changement en chaîne de manière satisfaisante. / The aim of this thesis is to formalise historical chain shifts within modern phonological theories. Martinet (1952, 1955, 1970) distinguishes two main categories of chain shifts: push chains and pull chains. Push chains will be dealt with in the first main part of this thesis (chapters 2 and 3). For modelling of push chains, an existing model is used: Łubowicz's (2003, 2012) Contrast Preservation Theory. For modelling pull chains, which will be the focus of the second part of this thesis (chapters 4 and 5), a new theory will be proposed, based on the phonetic work by De Boer (2001). This proposition is based on the notion of the pillar domains (domaines piliers). Chapter 1 starts with the observation that neither the derivational, SPE-like, theories or output driven theories like Prince's & Smolensky's Optimality Theory (OT) are able to formalise chain shifts properly. Within the derivational theories, it is possible to get a correct description of a chain shift. However, in order to do that, we have to break the links between the different stages of the chain shift. Therefore, one loses the systemic interdependence of the different stages, which is the essence of the chain shift. As regards to Optimality Theory, it is the two-level structure of the theory which proves problematic for chain shifts. In a theoretical chain shift such as /a/ → [e] > /e/ → [i], it is impossible for OT to make, in the same analysis, [e] an optimal candidate and /e/ a non-optimal one. In chapter 2, we analyse and compare several output-driven propositions that have been made to account for chain shifts. Many of them are not satisfactory because they do not manage to model the systemic motivation of chain shifts. The only theory that seems able to complete this objective is Łubowicz's Contrast Preservation Theory (CPT). This theory is based on the notions of contrast, contrast preservation and it evaluates scenarios rather than individual candidates. Contrast preservation is achieved through contrast transformation. The term contrast transformation indicates that the contrast levels of the input system are preserved but that their nature is different in the output system. One observation about CPT is that Łubowicz designed it for synchronic chain shifts. In chapter 2, we prove that CPT is able to model the perceptible coherence in diachronic chain shifts. In chapter 3, thus we decide to test the validity of CPT on actual historical chain shifts. It is tested on two cases. One is the well-known vocalic chain shift the Great Vowel Shift in English. The other one is the Second German Sound Shift (or High German Consonant Shift). We demonstrate that CPT is able to account for both of these chain shifts. At the end of chapter 3, CPT is tested on another type of chain shifts, i.e. chain shifts in first-language acquisition. The studied chain shift is s → θ → f. This chain shift is different from the other two because there is no new contrast level created. The last stage of this chain shift ends with a merger . Once again, CPT can account for this chain shift in a coherent way.

Comment les Tahitiens ont-ils conceptualisé le ciel pour en faire un instrument de mesure astronomique ? Leurs traditions apportent des explications sous forme de récits cosmogoniques. Ils peuvent nous envoûter mais, ils ne sont pas considérés comme des solutions scientifiques. L'astronomie a accordé aux théories qui ont cours aujourd'hui toutes les apparences du sérieux et de la rationalité. La cosmogonie a commencé le jour où l'homme s'est posé des questions sur son environnement et ses origines. Il fallait demander à ceux qui avaient voyagé, de raconter ce qu’ils avaient vu et entendu sur les régions encore plus lointaines. Les Tahitiens font partie de ces curieux qui sont allés voir ce qu’il y avait au-delà de l’horizon et pour qui la parole d’un ancêtre était acte de foi. Les réponses se trouvent donc dans les récits mythiques et le vocabulaire utilisé, à la source des symboles intellectuels. Pour les déchiffrer, l’approche linguistique est indispensable.Dans la cosmogonie tahitienne, le dieu Ta’aroa crée le monde. Le ciel demeure cependant uni à la terre, il le soulève à l’aide de dix piliers (pou), que repèrent des étoiles appelées ‘anā. Les objets célestes peuvent ainsi émerger des abysses à l’horizon et se mouvoir sur le dôme en traçant une dizaine de chemins (rua), guidés par les plus remarquables d’entre eux, les ta’urua. Cette conceptualisation du ciel offrira aux Tahitiens un instrument de mesure spatiotemporel remarquable.Leur lexique astronomique comporte près de deux cents termes porteurs de concepts. Les revisiter conduit à découvrir leur ancienne science. / How did the Tahitians conceptualize the skies in order to create their own instrument of astronomy? Traditions provide explanations in the form of cosmogony stories. They can entice or by no means are they considered scientific evidence. Astronomy has supported theories that give today a certain seriousness or rationality.Cosmogony began the day when man inquired about its environment and its origins. To fully understand, they asked those that have travelled in the past, recollecting descriptions of what they had seen and heard from faraway places.The curiosity of Tahitians has pushed them to travel beyond the horizon having only faith in the words of their ancestors. The answers can be found within the mythical recitals by understanding the vocabulary used at the source of intellectual symbols. Without a doubt, the approach of a linguist is necessary.In Tahitian cosmogony, the God Ta'aroa created the world. The sky was attached to the earth and in order to separate them; he used ten pillars "Pou", that are marked by stars in the sky called "'Anā". Celestial bodies move across the dome sky by following pathways called "Rua" and each pathway is highlighted by a dominant star called "Ta'urua". This conceptualization of the sky gave Tahitians a remarkable instrument for measuring space and time. The lexicon of astronomy terms numbers nearly two hundred. Understanding them leads one to discover their ancient science.
