Discrete Voss surfaces: Designing geodesic gridshells with planar cladding panels

Corentin Jean Dominique Fivet, Nicolas Robin Montagne, Olivier Baverel

The design and construction of doubly-curved structures often reveals to be challenging and can result in complex manufacturing and assembly. A recent strategy to tackle this difficulty consists in exploiting the connection between discrete differential ge ...

Upcycling Space Structures (Preface to special issue)

Corentin Jean Dominique Fivet, Olivier Baverel

The construction industry’s contribution to the deterioration of Earth’s ecosystem is huge. 11% of all anthropic greenhouse gas emissions worldwide are due to the construction, demolition, and transformation of buildings and infrastructure. Construction an ...

Voss surfaces: A design space for geodesic gridshells

Corentin Jean Dominique Fivet, Nicolas Robin Montagne, Olivier Baverel

The design of envelopes with complex geometries often leads to construction challenges. To overcome these difficulties, resorting to discrete differential geometry proved successful by establishing close links between mesh properties and the existence of g ...

Generation of elastic geodesic gridshells with anisotropic cross sections

Corentin Jean Dominique Fivet, Nicolas Robin Montagne, Olivier Baverel

Geodesic gridshells are shell structures made of continuous elements following geodesic lines. Their properties ease the use of beams with anisotropic cross-sections by avoiding bending about their strong axis. However, such bending may arise when flatteni ...

Experimental investigation of beams under coupled bending and torsion

Corentin Jean Dominique Fivet, Nicolas Robin Montagne, Olivier Baverel

The design of doubly-curved systems called for innovative modelling techniques to evaluate the final geometry of the structure. They can simulate the behaviour of beams under large displacements. Even though it is never analysed, the deformation path is ca ...

Form-Finding Of Interlaced Space Structures

Yves Weinand, Seyed Sina Nabaei, Olivier Baverel

By Interlaced Space Structures (ISS) we mean a coupled system of naturally curved flexible panels/strips interlaced together according to a design pattern. We are looking for a physically-based and efficient form-finding procedure in order to interactively ...

Form finding of twisted interlaced structures: a hybrid approach

Yves Weinand, Seyed Sina Nabaei, Olivier Baverel

Our study presents a set of form-finding procedures to explore curved structures made from interlaced panels. Interlacing introduces a particular coupling between assembly components which has to be formulated along with a pertinent flexible body model. We ...

Mechanical form-Finding of the Timber Fabric Structures with Dynamic Relaxation Method

Yves Weinand, Seyed Sina Nabaei, Olivier Baverel

Timber Fabric structures (TFS) initiate from a correspondence between textile principles and recent industrial developments in producing cross laminated timber panels. Several individual timber strips are interlaced according to a pattern and result in an ...

Geometrical description and structural analysis of a modular timber structure

Yves Weinand, Seyed Sina Nabaei, Olivier Baverel

The ambitious goal of the ongoing research at IBOIS, the Laboratory of timber constructions at the Ecole Polytechnique Fédérale de Lausanne (EPFL) is to develop a next generation of timber constructions made out of innovative timber-derived products, throu ...
