“…The idea was that it could be customizable for the structure shape and tubular bars. The connection was divided into 2 parts: first, the global definition of the contact surfaces, supports, and fitting angles; and second, the definition of the geometry of the parts (Oliveira et al 2020).…”

Structural systems built from raw bamboo have been used for years due to its highly renewable characteristics, versatility, and abundance in various countries, e.g., China, Indonesia, all over South America, and especially Brazil. It is also considered a low specific weight material, which means it is easy to handle and transport. These characteristics make it a low-cost material for building construction. The objective of this systematic bibliometric review is to identify innovations in bamboo culms structural connections in order to contribute to the advancement of technology applied to civil construction by seeking joints that consider the use of industrialized or standardized products. This review revealed there is still no ideal connection capable of solving the great problem of this subject, which points out the need for more studies on the topic. This investigation also allows for the classification of the connections into 5 categories: Bolted connections; Steel member and Steel plate connections; Reinforced Connections with filler; Parameterized connections, and; Connections with the use of wooden dowels.

“…As opposed to these two common approaches, the main focus of this paper is to develop nodes as visible objects. Research that develops nodes as visible objects also exists, and this research often focuses on possibilities with manufacturing with 3D printing; see de Oliviera et al, 24 Crolla et al 25 and Seifi et al 12 Other examples ivestigate an assembly of 3-axis machined plate, like in Lienhard et al 26 Apart from these recent examples, most development of gridshell nodes as visible objects happens in the industry, like from Lanik Structures 27 and Mero Structures, 28 as formerly pointed out by the author. 1 This study proposes a set of node principles for timber gridshells with aluminium nodes.…”

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 methods and based on this, a set of novel node principles in aluminium are deducted and proposed for a timber gridshell on the geometry of the British Museum Great Court. A finite element analysis is done on the proposals to increase the understanding of the node principles’ structural behaviour and feasibility. Together, the set of node principles, their evaluation and the utilised procedure can provide new options in the future design of gridshells and gridshell nodes.

“…The shortcoming of building based on preestablished universal kits of parts is the limited design freedom. Attempts to mitigate this issue have produced "universal joints" (Rochas, 2014) or adaptive parts (de Oliveira, Pauletti and Meneghetti, 2020) that trade between structural stiffness, reusability and design freedom (applicability) often with mixed results. Other approaches have looked to probe the limits of kit design by building dedicated computational construction frameworks for dedicated toy construction kits like the ZomeTool (Zimmer et al, 2014) or have produced computational strategies (Brütting, Senatore and Fivet, 2021) to construct a kit of spherical nodes and bars able to accommodate the construction of several reticular structures with distinct geometries and topologies, thus sharing one single set of resources among multiple constructions that are chronologically distinct.…”

Sustainable temporary architecture seems like a dichotomy but should be a major concern for the construction industry. Now aware of its impact, architecture must contribute to a more sustainable management of resources and despite their short time frame, ephemeral structures should be no exception to the rule. This work aims to develop a simpler and more accessible computational workflow based on the particle system tool Kangaroo inside Grasshopper to match design intent with available material stock. The proposed research examines the potential of combining raw or reused materials, such as wood and plastic, with easily accessible architectural technologies and tools to generate temporary and sustainable constructions. The workflow allows for many design variations using only simple and intuitive tools in both its digital and physical stages and aims to support the simple development non-standard, responsible temporary architecture that fully implements the principles of a circular economy.
