Konferensbidrag (refereegranskat)abstract
- This paper describes and discuss the design, fabrication and assembly of an asymptotic gridshell built of plywood laths. The overall question concerns how geometry, structural action, and ecient production can interplay and inform spatial design. The environment is a two-day workshop where architects, engineers and researchers with specialization in structural and digital design cooperate with undergraduate students in a compulsory parametric design and digital fabrication course. The gridshell shape is based on an Enneper surface of threefold rotational symmetry with a boundary baseplate inscribed within a circle of 4.5 m in radius. Utilizing the concept of asymptotic curves, which are surface curves whose osculating plane coincides with the tangent plane of the surface, the structure was built using planar straight laths of plywood made using manually operated drills and saws.

Design, fabrication and assembly of a geodesic gridshell in a student workshop
- 2018
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper describes the design, fabrication and assembly of an 11x11 m gridshell built of plywood laths during a two and a half day workshop in a new undergraduate course about parametric design and digital fabrication. The question was how to use full-scale prototyping to summarize and integrate the learning outcomes in this course. A challenge was how to execute all production during two consecutive days utilizing all 35 students. Exploiting a geodesic grid design, that is curves whose curvature vector is parallel with the surface normal, the gridshell was made of straight predrilled laths that were bent and locked into shape using a sequential erection method. The design was incorporated in a full parametric model including automated design checks and the generation of all necessary production drawings.The workshop and the preparatory work described in this paper was a collaboration between Chalmers, BIG Engineering, Buro Happold and Thornton Tomasetti's CORE studio.

An experiment of using non-rigid falsework in construction of brick vaults
- 2018
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- This video is showing an experiment that was performed to evaluate the possibility of using flexible, or non-rigid, falsework for formfound arches and vaults. Traditionally falsework are made from stiff templates out of wood but for complex shapes this might require expensive CNC machines. The video is showing the preparatory work for a workshop at crafts school, Dacapo, in Mariestad in 2016, where students were to be learning traditional crafts but also a test to see how digital tools could be incorporated in crafts. The falsework was made from plastic tubes which were measured to make the right cut lengths and connections based on a digital model which was generated based on a gravitational load. For a small vault like this the capacity and stability of the plastic tubes was sufficient, but for larger shells or vaults more calculations and investigations are needed.

Brick patterns on shells using geodesic coordinates
- 2017

Konferensbidrag (refereegranskat)abstract
- We present two separate strategies for generating brick patterns on free form shells and vaults using geodesic coordinates. The brickwork is specified by a surface on which there is a geodesic coordinate system satisfying the condition for a constant distance between bed joints. The first strategy integrates the generation of the geodesic coordinates in a form finding procedure derived from the geometrical and mechanical properties of a shell. The geometric and structural equations are solved using dynamicrelaxation. The second strategy can be applied on an arbitrary surface separating the form

Differential geometry and structural action of vaults and shells
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Masonry vaults and bridges, concrete shells, and steel and timber grid shells are all examples of shell structures. Their beauty, spatial qualities, structural efficiency and manufacturing are closely tied to their geometry. Geometry is central since it does not only describe the shape of the shell but also the building blocks, which together form a pattern or grid dictating its construction and structural behaviour. History has shown how architects and builders successfully utilized curved shapes to combine architectural qualities with structural efficiency through the use of simple building blocks of local materials. Differential geometry offers a mathematical framework for the investigation of such architectural qualities in both historic and new structures. The focus of this thesis is to investigate how differential geometry can contribute to the design and production of shell structures in the digital age . During the thesis work, different directions for the investigation of differential geometry in architecture and engineering have been explored. Out of these explorations, two main directions have evolved, each of them with a more limited and specific research question: How can differential geometry be used to design structurally efficient shells and shells with surface patterns for simple production? How can differential geometry be applied in a design process supporting the quick production of a grid shell? These questions have been treated and investigated in studies reported in the appended Paper A-F. Paper A, D and E cover different aspects of how to design shells where simple building blocks can be used. Paper A and D show different possibilities for designing new brick shells and masonry bridges, while Paper E investigates the architectural application of shells whose boundaries subtend a constant solid angle. Paper B and C describe and discuss the design and construction process of two different timber grid shell structures built of straight planar laths. Paper F takes its point of departure from the fact that shells are generally statically indeterminate structures, allowing several force and moment distributions that can fulfil equilibrium. Our study offers a framework for designing shells using the force method, where the redundant forces and moments in the shell are represented as two surfaces.

Geometry linking the art of building and the Universe: Geometric patterns on shells and grid shells
- 2021
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Geometry links the art of building and the physics of space-time. Mathematical breakthroughs in geometry have led to new ways of designing our structures and our ability to visualise and describe the world, phenomena in nature and the universe. However, in contemporary architecture and structural engineering, a more profound understanding of geometry has been forgotten. This thesis aims to resurrect geometry in architecture and engineering in connection with the rapid development of new digital tools for design and production—particularly the connection between the structural action related to the design of the geometrical patterns on shells structures are treated. A brief historical overview of geometry is conducted, and with an emphasis on its applications in architecture in terms of structural design and economic production. Furthermore, the connection to a sustainable building culture from the standpoint of the Davos declaration 2018, calling for a high-quality Baukultur is investigated. The concept of Baukultur (building culture in English) defined in the Davos declaration is related to architectural quality but has a broader meaning as it concerns the final product and the associated processes and its effect in society. Moreover, the concept of craftsmanship and workshop culture is examined, and how it is already present in computer code development and contemporary innovative research cultures combining architectural design and technology. Taking departure from the 18th-century experimental scientist Joseph Plateau and the contemporary artist Andy Goldsworthy, the connection between scientific and artistic research is investigated. Four articles are included; all connected to various ways of architectural applications of geometry in the design process. The first article describes a way to interpret empirically derived brick patterns, specifically the bed joints, using differential geometry. Two methods to apply this in the design processes of new brick vaults are presented. The first is purely geometrical and can be applied on an arbitrary shape with the possibility to apply several patterns; the second is an iterative method of generating a funicular shape and its pattern simultaneously. The second and third paper describes the design and construction process of two different wooden structures built of straight planar laths. Both studies examine the possibilities of using geometry as a link between various parameters in a design process using digital tools to achieve complex forms using simple elements and production methods. The fourth paper examines an appropriate form for a shell, that can balance aesthetics, structural performance and build-ability, with a proposal for the use of surfaces with constant solid angle. In this paper, the surface was generated with a Delaunay triangulation. Thus, future studies would include incorporation of other types of patterns facilitating buildability.
