Freeform structures can provide both aesthetically interesting and material efficient solutions but are considered a demanding task for both structural design, manufacturing and architectural design. A free form surface is therefore rationalized into something more buildable like the gridshell. However, a digital design process with freeform geomet...

Aluminium as a structural material is favourable in many applications, however, aluminium in architecture is seldom structural. Aluminium benefits from being durable, corrosion resistant and light weight, but challenges regarding fire protection, high embodied energy and high costs makes it less favourable. In addition, lower strength than steel of...

Gridshells are shells where the structural system is some kind of grid of linear members rather than a surface. With today’s focus on environmentally friendly solutions, gridshells have gained increased relevance as inherently material-efficient structures. This paper investigates the recent research on gridshells, who performs it and what their co...

Linking architectural models to structural analyses can be demanding and time-consuming, especially when the architectural models cannot be accurately analysed using readily available one- or two-dimensional finite elements. This paper presents a tool for finite element analysis using solid elements developed as a plugin for Grasshopper 3D® that en...

Gridshell nodes are key elements regarding structural performance, visual appearance and assembly of any gridshell that have been given little attention in recent research. This paper explores aluminium as a material for timber gridshell nodes. First, existing gridshell nodes are categorised regarding bulk materials, gripper types and connection me...

Algorithms-Aided Design, a computational design methodology, has seen a seen an increased interest in the past decades. Especially for complex free-form geometries such as gridshells. The growing potential of controlling the design through algorithms allows for merging structural and architectural design methods by creating customised design tools...

In the early stages of a design, the project's structural behaviour and rational use of the material is not always a primary area of interest for the architect. Moreover, most software developed for this purpose is created for and by structural engineers. Consequently, the architect's initial idea may be unrecognisable after several rounds of optim...

Even though Nordic glulam truss-bridges are at large extent standardized, applying dowels and parallel slotted-in steel plates, the process making them are still separated and slowed down by redundant work. This paper examines the potential of architects, engineers and manufacturers using a shared parametric framework when building truss-bridges. H...

This paper discusses and describes the geometry and manufacturing of nodes in free form reticulated shell structures. Reticulated shells are commonly produced with steel nodes, providing new design solutions aluminium has different manufacturing constraints. The paper presents manufacturing methods for mass customized aluminium nodes and discusses...

p>The fourth industrial revolution, already present in the several industries, is now entering the field of civil engineering. Digital fabrication, mass customization, robot arms and drones are connected within the building information modeling (BIM) systems. All the work that is currently accomplished by nonprofessional or semi-professional worker...

The building industry is about to embrace mass customization. In recent years, iconic buildings have demanded a new way of approaching design and manufacturing. We, among others, believe that parametrization is key to fully exploiting mass customization in building industry. This study presents an early beta-version of an interdisciplinary parametr...

This paper explains the construction scheme of a modular post formed gridshell. The scheme uses timber modules connecting laths of 900 mm length into a 2-layer module. The scheme and the module are designed to efficiently handle both Form Finding, Fabrication and Raising, and they are tested through the construction of a full scale pavilion in Tron...

The paper introduces a kinematic gridshell principle built with the smallest possible module. The module consists of only two laths providing one node and the four connectors to adjacent nodes. The solution is named the segment lath and the result is a system able to construct any quadratic grid shape using only one module type. Among other assets,...

The structural performance of gridshell structures is strongly related to shape, but comparisons between design and construction shape are seldom reported. This paper documents the evolution of shape following the erection of a timber gridshell built in Norway. Structural performance was evaluated using experimental measurements, and was observed t...
