Great architecture exists by creating an equilibrium between the experiential world and the intellectual world. On one hand these two worlds operate at polar opposites, while on the other hand these two worlds are totally dependent on one another’s existence. Through the conscious pursuit of reconciling these differences, the creation process is open to its fullest realm of possibilities and complexities. Le Corbusier used the intellectual world to gain the experiential. Although, in his later years, this process began to reverse itself. Alvaro Siza uses the experiential world to gain the intellectual. While these processes are pursued from opposite extremes, the final works reach a common goal. That goal being a complete fusion of the experiential and intellectual worlds which allows these works to procure a vital new spirit. One other case needs to be mentioned here. This being the case of Alvar Aalto. Aalto was pure genius in his understanding the significance and consequences of unifying the experiential and intellectual worlds. As a result, I believe Aalto's starting point was where the reconciliation of these two worlds occurs. By starting at this point, Aalto allowed himself the enormous freedom of reaching out simultaneously to both the experiential and intellectual worlds, extracting whatever components were necessary to create his wonderful works of art. A major objective for me is to simultaneously reconcile the experiential and intellectual worlds into a harmonious equilibrium. The moment this harmonious equilibrium occurs is the point where architecture is on the threshold of beauty / Master of Architecture

This thesis choreographs the procession around and within a tower. An alternating sequence of compression and expansion of space creates a rich spatial experience. Each moment along the sequence is meant to complement or contrast the others, exaggerating their effect. The tower's form is designed by producing and then selecting from a series of potential solutions. Each iteration is guided by the aforementioned sequence of spatial conditions. / Master of Architecture

Des bâtiments de grande hauteur sont construits avec un poids et un amortissement structurel de plus en plus faibles en lien avec l'évolution des techniques de construction et des matériaux. La connaissance des charges de vent dynamiques est un enjeu important pour la conception des grands bâtiments afin de garantir leur sécurité structurelle. L'objectif de cette thèse est d’évaluer la capacité de la simulation numérique des grandes échelles (LES) à prédire les charges de vent sur les structures et d’étudier l'influence des conditions d’entrée d’une simulation LES sur ces charges. Des expériences ont été menées à échelle réduite dans la soufflerie atmosphérique NSA du CSTB afin de documenter l’écoulement atmosphérique modélisé, de caractériser son interaction avec un bâtiment et les charges de vent statiques et dynamiques résultantes. Le sillage du bâtiment a été caractérisé grâce à des mesures PIV. Les efforts globaux et les pressions locales ont été mesurés par une balance et des prises de pression à haute fréquence. Ces expériences en soufflerie ont permis de développer un générateur de conditions amont (GCA) pour la simulation LES, visant à reproduire les principales caractéristiques de la turbulence dans la couche limite. La base de données constituée a également permis de qualifier les résultats des simulations LES réalisées avec le code OpenFOAM dans la configuration de l’expérience. L’utilisation du nouveau GCA et d’un générateur dégradé qui ne respecte pas toutes les caractéristiques de l'écoulement a permis de montrer la nécessité de bien reproduire les caractéristiques du vent incident pour accéder aux charges dynamiques sur le bâtiment. / High-rise buildings are built with increasingly low weight and structural damping in relation to the evolution of construction techniques and materials. The understanding of dynamic wind loads is an important issue for the design of high-rise buildings in order to guarantee their structural safety. The objective of the present work is to assess the ability of large eddy simulation (LES) to predict wind loads on structures and to investigate the influence of the inflow boundary conditions of a LES simulation on these loads. Experiments were carried out at a small scale in the NSA atmospheric wind tunnel of CSTB to document the modeled atmospheric boundary layer, to characterize its interaction with a building and the resulting static and dynamic wind loads. The wake flow around the building has been characterized by PIV measurements. Global and local wind loads were measured by a high frequency force balance and high frequency pressure taps. These wind tunnel experiments allowed for the development of an inflow turbulence generator for the LES simulation,which was aimed at reproducing the main characteristics of turbulence in the boundary layer. The database also made it possible to assess the quality of the results of the LES simulations carried out with the OpenFOAM code in the same configuration as the experiment. The use of both the new turbulence generator and a degraded one that does not account for all the characteristics of the flow has made it possible to show the necessity to reproduce the characteristics of the upstream wind flow in order to access the dynamic wind loads on the building.

The aim of my PhD project has been to understand how Hutong residents' ideas about living space have been different from those living in the high-rise compound and how their concept of living space has been changed by both internal and external factors, meaning additional affiliated functions and governmental city-planning. I conducted my fieldwork in Beijing between July 2009 and September 2012: fourteen months in total, interspersed with trips to St. Andrews. I spent ten months from July 2009 to May 2010 living in a Hutong called Xingfu Street (the word translates as ‘happiness'). Then I moved into a high-rise apartment outside the inner city, called Suojiafen Compound, for a further four months. This study concerns space in the contemporary city of Beijing: how space is humanly built and transformed, classified and differentiated, and most importantly how space is perceived and experienced. In the end I have developed the concept “overlapped” space as a way to detect the “personality” of space in both Hutong and high-rise apartment: how they differentiated from each other and how they have been transformed in different way by the residents inside.

Le présent travail propose et développe une méthode originale de dimensionnement vis-à-vis de l'incendie de parois de bâtiments industriels, en s'intéressant plus spécifiquement au cas des panneaux en béton armé de grande hauteur. Soumis à un fort gradient thermique, ces derniers subissent en effet des déplacements hors plan importants qui, du fait de l'excentrement du poids propre qui en résulte, vont engendrer des efforts de flexion venant s'ajouter aux efforts de compression déjà existants. Un tel changement de géométrie, d'autant plus prononcé que le panneau est de grande hauteur, combiné à une dégradation simultanée des propriétés de résistance des matériaux sous l'effet de l'élévation de température, peut conduire à un effondrement de la structure sous poids propre, bien avant par exemple l'apparition d'une instabilité de type flambement. L'approche proposée repose très largement sur la théorie du Calcul à la Rupture, appliquée d'une part à la détermination d'un diagramme d'interaction au feu caractérisant la résistance du panneau en chacune de ses sections, d'autre part à l'analyse de la ruine globale du panneau dans sa configuration déformée. Cette démarche est d'abord mise en œuvre et complètement explicitée dans le cas où le panneau peut être modélisé comme une poutre unidimensionnelle, conduisant à la détermination exacte d'un facteur adimensionnel caractérisant la stabilité de ce dernier. La généralisation de la méthode de calcul à la configuration plus réaliste, mais plus complexe, d'un panneau schématisé comme une plaque rectangulaire, est ensuite développée. Elle aboutit à un certain nombre de résultats préliminaires qui devront être confortés et affinés dans un travail ultérieur. L'approche théorique ici présentée est par ailleurs complétée par un volet expérimental (essais de flexion quatre points de dalles dans un four à maquette) qui a permis de valider au moins partiellement les évaluations du diagramme d'interaction prédites par le calcul / In this contribution, an original and comprehensive method aimed at designing vertical concrete walls submitted to fire loadings, is proposed and developed, with a special emphasis on high rise panels used in industrial buildings. Indeed, when subjected to high thermal gradients, such slender structures exhibit quite significant out-of-plane movements, resulting in an eccentricity of the gravity loads and thus to bending moments in addition to the pre-existing compressive forces. It is such a change of geometry, which is all the more pronounced as the panel is tall, combined with a temperature-induced degradation of the constituent materials strength properties, which may explain why an overall collapse of the structure may occur, well prior to buckling instability. The proposed approach is fundamentally based on the theory of yield design. This theory is first applied to the determination of an interaction diagram, characterizing the fire resistance of a reinforced concrete panel cross-section. It is then implemented as a design method for analysing the stability of the panel in its previously calculated deformed configuration. The whole procedure is explained in full details in the simplified situation when the high rise panel can be modeled as a one-dimensional beam, leading to the exact determination of a dimensionless factor characterizing the stability of the panel. The method is then extended to deal with a more realistic, but somewhat more complex, configuration of a rectangular panel. Some preliminary results, which need to be further validated in a subsequent work, are finally produced. As a necessary complement to the mostly theoretical and computational approach presented in this work, a series of four-point bending tests has been performed on reduced scale slabs placed in a furnace. The results of these tests partially validate the predicted interaction diagram of a fire loaded panel section

The thesis is about static analysis of moving skyscraper (inspired by The Dynamic Tower). There is a rotation of each particular floor around its axis independently on each other. In this thesis, moving skyscraper is solved as a whole piece with specialization in the moving floors and their mounting on the core of the building.

Aim of The Diploma Thesis was to design load-bearing structure of a multi-storey reinforced concrete building, to realize structural analysis in Dlubal-RFEM software and dimension its selected parts. Designed structure is based on already erected building in office edifices campus in Brno-Slatina district. Its original number of storeys was increased from ten to nineteen, so the specific problems connected to high-rise building designing could be solved. Time dependent deformations of vertical structures were analysed in detail, so the changes in load of horizontal elements could be described more precisely, because of its direct dependence on compression of the columns. Within the paper, foundation structure dimensions were designed, assessment and design of composite columns assembly were made, as well of floor slab in 2nd floor with column deformations impact check on the 17th floor. Also, the external walls, pillars and shear core walls were designed and assessed. Formwork drawing of designed structure parts and detailed drawing of reinforcement of assessed elements were elaborated. Based on Diploma Thesis results it can be stated, that if influence of nonuniform load of vertical structures within the high-rise building designing is neglected, consequent project would presumably be uneconomic, or dangerous after an optimization attempts.

The focus of this thesis is to deal with reverse engineering of high-rise building settlements. This is modeled via the finite element method performed in the Plaxis 3D program. In the first part of this thesis, a calibration of input parameters of an appropriate material model – Hardening soil – is conducted. This calibration is a result of oedometric test data which were obtained within a geotechnical survey. An influence of soils over consolidation affecting calibration and the material model choice is described. Final values of reference stiffness parameters are used in a mathematical model of the focused area. This model is created for one half of the high-rise building plan, including vestibule. The high-rise building is founded in a foundation pit. The foundations of this building consist of raft foundation and piles of jet grouting. In the model, there are also changes in pore pressure during an excavation of foundation pit included. The functional model is used for parametric analyses, namely examining cases of object´s foundations and the possible influence of foundation pit´s symmetry on the object´s settlement. All the calculated processes in the object´s settlements are then compared to data obtained from geotechnical monitoring of the structure.
