Achieving a pure-compression stress state is considered central to the form-finding of shell
structures. However, the pure-compression assumption restricts the geometry of the …

Additive manufacturing (AM) for metals is rapidly transitioning to an accepted production
technology, which has led to increasing demands for data analysis and software tools. The …

Owing to the rapid development in additive manufacturing, the potential to fabricate intricate
structures has become a reality, emphasizing the importance of designing structures …

A shape design method is proposed for free-form shells specifying the distribution of
horizontal reaction forces along the boundary as well as the stresses projected to the …

A two-stage form-finding procedure, based on Isogeometric Analysis (IgA), is proposed to
determine the configuration of shells having a prescribed planar footprint so as to carry …

The paper presents a new method for constructing self-supporting surfaces using arch
beams that are designed to convert their thrust into supporting force, thereby eliminating …

A two-step form-finding strategy for determining the heights of a shell of a given plan-form is
presented. The shell heights are determined in such a way that the structure can equilibrate …

The performances of gridshells depend on the topology of the grid but also on the geometry
of the underlying surface. Topology and geometry are linked: the shape of a hanging chain …

A numerical form-finding procedure, based on Isogeometric Analysis (IgA), is proposed to
determine the elevation of a shell having a prescribed covered area so as to carry applied …

This paper presents a form finding method for free-form shells that specifies the distribution
of stresses projected onto the horizontal plane. The vertical coordinate of the shell surface is …
