Morphogenesis of Curved Structural Envelopes Under Fabrication Constraints École doctorale Science, Ingénierie et Environnement Manuscrit préparé pour l’obtention du grade de docteur de l’Université Paris-Est Spécialité: Structures et Matériaux Morphogenesis of curved structural envelopes under fabrication constraints Xavier Tellier Soutenue le 26 mai 2020 Devant le jury composé de : Rapporteurs Helmut Pottmann TU Viennes / KAUST Christopher Williams Bath / Chalmers Universities Présidente du jury Florence Bertails-Descoubes INRIA Directeurs de thèse Olivier Baverel École des Ponts ParisTech Laurent Hauswirth UGE, LAMA laboratory Co-encadrant Cyril Douthe UGE, Navier laboratory 2 Abstract Curved structural envelopes combine mechanical efficiency, architectural potential and a wide design space to fulfill functional and environment goals. The main barrier to their use is that curvature complicates manufacturing, assembly and design, such that cost and construction time are usually significantly higher than for parallelepipedic structures. Significant progress has been made recently in the field of architectural geometry to tackle this issue, but many challenges remain. In particular, the following problem is recurrent in a designer’s perspective: Given a constructive system, what are the possible curved shapes, and how to create them in an intuitive fashion? This thesis presents a panorama of morphogenesis (namely, shape creation) methods for architectural envelopes. It then introduces four new methods to generate the geometry of curved surfaces for which the manufacturing can be simplified in multiple ways. Most common structural typologies are considered: gridshells, plated shells, membranes and funicular vaults. A particular attention is devoted to how the shape is controlled, such that the methods can be used intuitively by architects and engineers. Two of the proposed methods also allow to design novel structural systems, while the two others combine fabrication properties with inherent mechanical efficiency. The feasibility of these new structural morphologies is demonstrated by the construction of two research pavilions. A video presentation giving an overview of this doctoral work can be found online at the following URL address: https://doi.org/10.5281/zenodo.3956351 Résumé Les structures à double courbure allient performance mécanique et expressivité architecturale. Elles offrent également de vastes possibilités formelles permettant dans un projet d’atteindre à la fois des critères fonctionnels et environnementaux. Le principal obstacle à leur utilisation est la complexité qu’elles engendrent, tant du point de vue de la fabrication et de la mise en place que de la conception. D’importants progrès ont été accomplis récemment sur cet aspect par le récent domaine de la géométrie architecturale. Cependant, il reste de nombreux défis. En particulier, du point de vue d’un concepteur, le problème suivant revient régulièrement : quelles formes sont réalisables avec un système constructif donné ? Comment atteindre ces formes de façon intuitive ? Cette thèse commence par présenter un panorama des méthodes de morphogenèse, c’est-à-dire de création de forme, sous contrainte de fabrication. Puis, quatre nouvelles méthodes de génération de forme sont introduites. Elles permettent chacune d’obtenir des propriétés constructives simplifiant les procédés de fabrication. Les principales typologies de structures courbes sont considérées : gridshells, membranes tendues, voutes maçonnées, et coques discrètes. Une attention particulière est accordée à la façon dont les formes sont contrôlées, afin de garantir une génération intuitive. Parmi ces méthodes, deux permettent de concevoir de nouveaux systèmes structurels, et deux autres permettent de combiner propriétés mécaniques et efficacité mécanique. Leur potentiel est démontré par la construction de deux pavillons.

Introduction When geometers talk of polyhedra, they restrict themselves to configurations, made up of vertices. edqes and faces, embedded in three-dimensional Euclidean space. Indeed. their polyhedra are always homeomorphic to thè two- dimensional sphere S1. Here we adopt thè topologists* terminology, wherein dimension is a topological invariant, intrinsic to thè configuration. and not a property of thè ambient space in which thè configuration is located. Thus S 2 is thè surface of thè 3-dimensional ball; and so we find. among thè geometers' polyhedra. thè five Platonic “solids”, together with many other examples. However. we should emphasize that we do not here think of a Platonic “solid” as a solid : we have in mind thè bounding surface of thè solid.

  • Polyhedral Surfaces, Discrete Curvatures, Shape Analysis, 3D Modelling, Segmentation
    JOURNAL OF MEDICAL INFORMATICS & TECHNOLOGIES Vol. 9/2005, ISSN 1642-6037 polyhedral surfaces, discrete curvatures, shape analysis, 3D modelling, segmentation. Alexandra BAC, Marc DANIEL, Jean-Louis MALTRET* 3D MODELLING AND SEGMENTATION WITH DISCRETE CURVATURES Recent concepts of discrete curvatures are very important for Medical and Computer Aided Geometric Design applications. A first reason is the opportunity to handle a discretisation of a continuous object, with a free choice of the discretisation. A second and most important reason is the possibility to define second-order estimators for discrete objects in order to estimate local shapes and manipulate discrete objects. There is an increasing need to handle polyhedral objects and clouds of points for which only a discrete approach makes sense. These sets of points, once structured (in general meshed with simplexes for surfaces or volumes), can be analysed using these second-order estimators. After a general presentation of the problem, a first approach based on angular defect, is studied. Then, a local approximation approach (mostly by quadrics) is presented. Different possible applications of these techniques are suggested, including the analysis of 2D or 3D images, decimation, segmentation... We finally emphasise different artefacts encountered in the discrete case. 1. INTRODUCTION This paper offers a review of work on discrete curvatures for Computer Aided Geometric Design applications and a discussion about some ideas for further studies. We consider the discrete curvatures computed on a set of points and their relevance to continuous curvatures when the density of the points increases. First of all, it is interesting to recall that curvatures are fundamental tools for studying curves and surfaces.

  • Elysée Wilson-Egolf Topic: Polygons, Polyhedra, Polytope Series
    Berkeley Math Circle Intermediate I, 1/23, 1/20, 2/6 Presenter: Elysée Wilson-Egolf Topic: Polygons, Polyhedra, Polytope Series Part 1 – Polygon Angle Formula Let’s start simple. How do we find the sum of the interior angles of a convex polygon? • Write down as many methods as you can. • Think about: how can you adapt your method to concave polygons? Formula for the interior angles of a polygon: _________________ . Q: There is an equality between the number of ways to triangulate an n+2-gon and the number of expressions containing n pairs of parentheses that are correctly matched. Prove that these numbers are the same. Can you find a closed formula? Part 2 – Platonic Solids and Angular Defect Definition: A platonic solid is a polyhedron which a. has only one kind of regular polygon for a face and b. has the same number of faces at each vertex. One simple example is that of a cube. Each face is a square (=regular quadrilateral) and each vertex is connected to exactly three squares. In Schläfli notation, this is {4, 3}: the regular polyhedron with 3 regular 4-gons at each vertex. • Can there be polyhedra with exactly one or two squares at each vertex? • Can there be polyhedra with exactly four squares at each vertex? For future reference, we’ll need the notion of the “angular defect” as well. Rather than focusing on what is present at the vertex, we focus on what is absent: the deviation from 360 degrees at the vertex, or “leftover” angle. In this case, it is 360−90×3=90 .

  • 2012 Annual Report
    AnnuAl RepoRt 2012 On the cover: Brighamia insignis, commonly known as ‘ālula or ‘ōlulu in Hawaiian, a critically endangered plant endemic to Kaua‘i. This Page: Bamboo Grove, Allerton Garden, Kaua‘i Message froM Chipper WiChMan and Merrill MagoWan 2012 was an important year for the National Tropical Botanical Garden in many ways. One of the most significant was the fact that it marked the first year of our new five-year strategic plan. This plan is our roadmap to achieving our vision and our potential as a leading botanic institution. The plan represents our dreams and aspirations for the future and the first year demonstrated great progress towards the challenging goals we set for ourselves. Two significant key goals of the plan call for the creation of an international center for tropical botany at The Kampong (our garden in Florida) in collaboration with Florida International University and the renewal and improvement of our flagship garden – McBryde Garden. Both of these goals will extend the impact of our organization to a national and international audience as well as help to create a more sustainable organization financially. Significant contributions were received in 2012 towards both of these goals. Another highlight of 2012 was the fall Board meeting held in the United Kingdom. In the 49-year history of our organization, this is the first time the Board has met outside of the United States. The meeting took us to the Eden Project in Cornwall and the Royal Botanic Garden Edinburgh in Scotland where they shared their expertise in innovation through marketing, visitor services and education.

  • Chapter 2 Figures and Shapes 2.1 Polyhedron in N-Dimension in Linear
    Chapter 2 Figures and Shapes 2.1 Polyhedron in n-dimension In linear programming we know about the simplex method which is so named because the feasible region can be decomposed into simplexes. A zero-dimensional simplex is a point, an 1D simplex is a straight line segment, a 2D simplex is a triangle, a 3D simplex is a tetrahedron. In general, a n-dimensional simplex has n+1 vertices not all contained in a (n-1)- dimensional hyperplane. Therefore simplex is the simplest building block in the space it belongs. An n-dimensional polyhedron can be constructed from simplexes with only possible common face as their intersections. Such a definition is a bit vague and such a figure need not be connected. Connected polyhedron is the prototype of a closed manifold. We may use vertices, edges and faces (hyperplanes) to define a polyhedron. A polyhedron is convex if all convex linear combinations of the vertices Vi are inside itself, i.e. i Vi is contained inside for all i 0 and all _ i i 1. i If a polyhedron is not convex, then the smallest convex set which contains it is called the convex hull of the polyhedron. Separating hyperplane Theorem For any given point outside a convex set, there exists a hyperplane with this given point on one side of it and the entire convex set on the other. Proof: Because the given point will be outside one of the supporting hyperplanes of the convex set. 2.2 Platonic Solids Known to Plato (about 500 B.C.) and explained in the Elements (Book XIII) of Euclid (about 300 B.C.), these solids are governed by the rules that the faces are the regular polygons of a single species and the corners (vertices) are all alike.

In keeping with Penzance’s wonderful location our theme this year is “Golowan – All at Sea” - a tongue in cheek invitation to celebrate our amazing maritime heritage, and reflect it in a blaze of nautical imagery. However, “All at Sea!” couldn’t be wider of the mark, as the focus of everyone has been to ensure that, while cherishing established traditions, new things are tried, new partnerships secured and Golowan goes from strength to strength. All the elements for a great weekend are here - the mid-summer torchlit procession, serpent dancing and fireworks, the manic Mock Mayor of the Quay ceremony, music and market stalls, parades… and so much more… Golowan’s Quay Fair offers all the fun of the fair on Battery Road from 21st – 25th June and – last, but not least – Golowan 2017 sees the return of the marquee in St Anthony’s Car Park where Big Tow Productions will host a range of events – including the Mock Mayor election.
