Structural Design Concept

The project examines the potential of polymer concrete applications and the production of wood/polymer concrete composite materials in the large-scale architectural production. This polymer concrete was cast with laminated wood materials to create structural stiff nodes. The necessary formwork was developed from the node geometry, thus eliminating the operation of the formwork removal. The CNC milled,3-layer spruce timber boards were fixed temporarily with screws, then filled with polymer concrete and thus rigidly connected. The cured polymer concrete/wood node has high structural capabilities, and can withstand both pressure and tensile forces.

The support system has been developed from the so-called Zollinger system, where small modules are prefabricated and joined to form a greater structure. We created a parametric model in the Rhinoceros and Grasshopper software, and tested virtually various subdivision densities and node sizes. The overall structure was evaluated with the structural analysis tool Karamba, the different heights of the lamellas arise from the constructive analysis of stresses and deflections under vertical and horizontal loading.

 

All 122 nodes were cast separately and bolted on-site. The geometry has been developed with the assistance of the software plugin Rhino Vault to develop a purely compressive load freeform shell. Therefore, no supporting formwork was needed for construction.

 

The construction was also based on preliminary investigations with polymer concrete at the University of Trier (Prof. Wieland Becker and Prof. Robert Thum). Bollinger Grohmann Ingenieure (Robert Vierlinger) supported this research with Structural and digital design experise.

The noHOME pavilion shall paraphrase the idea of a sheltered space, which at the same time does not satisfy the basic needs of a home (protection, sleeping, eating, living). It is conceived as an architectural opportunity to draw public attention towards the social problem of being without a home/homeland.

The aim of the design is to raise consciousness about implications of being homeless for the persons concerned and their perception in society. In order to achieve this, the design explores and evokes subjective feelings such as the lack of privacy and the missing of a protective interior, a certain ambiguity between inside and outside with varying degrees of exposure, the perception of a hostile environment leading to an aggressive contextual interface and a limitation of space without the provision of shelter functions to weather conditions.
