Conference Paper
Full-text available
Masonry bridges are among the most sustainable structures ever to have been built. The long service time, the resilience to carry larger loads than originally intended, and significantly lower life cycle cost compared to other bridge types suggest that we should consider the design and construction of new masonry bridges, even if their initial cost...
Conference Paper
Full-text available
We describe the flow of forces and moments across a shell starting from the Günther-Schaefer stress functions for a Cosserat continuum in 3 dimensions and Schaefer's concept of a Krustenschale or crust shell. We apply the idea of the flow of forces and moments to a shell in the shape of Enneper's minimal surface.

Surface geometry plays a central role in the design of bridges, vaults and shells, using various techniques for generating a geometry which aims to balance structural, spatial, aesthetic and construction requirements. In this paper we propose the use of surfaces defined such that given closed curves subtend a constant solid angle at all points on...
Article
Full-text available
We demonstrate that the internal forces and moments in a shell structure can be described by 4 vectors in 3 dimensional space which could be used to express the equilibrium of a shell graphically. The internal forces and moments described by 2 of the 4 vectors actively carry imposed loads and imposed couples, while the other 2 describe ‘redundant’...
Thesis
Full-text available
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...
Conference Paper
There are 4 fundamental 2nd order tensors in shell theory, firstly the stress and internal moment tensors which are in equilibrium with the applied loads and loading couples, and secondly the rate of membrane strain and the rate of bending tensors which are compatible with the velocity of the shell as it deforms. Shell theory is completed by the c...

Article
Pure-compression shells have been the central topic in the form-finding of shells. This study investigated tension-compression mixed-type shells by utilizing a NURBS-based isogeometric form-finding approach that analyses Airy stress functions to expand the possible plan geometry. A complete set of smooth version graphic statics tools is provided to...
Conference Paper
Full-text available
Masonry arch bridges for rail transport in Europe are still in use 200 years after they were built. Traditional masonry bridges support granular fill which in turn supports the roadway or railway tracks spreading the load on the arch. The stiffness requirements for high speed rail bridges mean that they have to be heavy, in which case masonry bridg...
Thesis
Full-text available
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 geomet...

Conference Paper
Full-text available
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 efficient production can interplay and inform spatial design. The environment is a two-day workshop where architects, engineers and researchers with specializatio...

Parametric model for the geodesic gridshell that goes from the form to the production drawings. Contains a grasshopper file(.gh) and a rhino file (.3dm).
Presentation
Full-text available
Presentation of the paper "Design, fabrication and assembly of a geodesic gridshell in a student workshop" at the annual symposium of IASS 2018 in Boston.
Conference Paper
Full-text available
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 w...
Conference Paper
Full-text available
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 coordinat...
Thesis
Full-text available
In this thesis, we propose a strategy for generating patterns for brick laying on compression free-form shells. The strategy is based on geodesic coordinates which guarantees an equal length between its coordinates curves, which for brickwork means an equal spacing between the bed joints. The implementation is done for polar geodesic coordinates us...
