HYPARCHE Modular Pavilion
These covered or semi-covered public spaces, varying in scale and serving diverse purposes, create venues for events in the neighborhood surrounding the Olympic Stadium. They can be used on a daily basis by residents and visitors alike, offering a wide range of possibilities: festivals, concerts, markets, shaded terraces, and green canopies that provide a lush, natural setting... These custom-designed structures bring to life temporary, semi-permanent, or permanent spaces that are shaded and partially or fully protected from the elements.
This versatile typology, featuring 5 to 12 modular canopies, allows for optimal use of available materials. The geometry of the canopies is configurable: their dimensions and proportions are adjustable, while certain factors remain fixed, such as the capacities and dimensions of the available sections. The structural elements inherited from the stadium's roof are displayed without artifice: reused connectors to build massive abutments, the generation of the canopy's surface determined by cable lengths, thus conferring a unique architectural language.
The self-supporting structures are placed on the ground without foundations; they are demountable, transportable, and can be reassembled here or elsewhere, allowing this legacy of the Montreal Olympic Stadium to be shared with other regions.
The structural principle is common to all variants. The geometry of the roof is a double-curved surface, a hyperbolic paraboloid or "hypar." This type of ruled surface can be constructed from straight elements. The roof grid consists of straight cable sections with a maximum length of 6 meters. They are assembled at the nodes via a circular connection: a section of the stadium roof's struts. This structural cable net is tensioned between inclined truss arches. These arches are made from sections cut from the stadium's perimeter beams.
The cable net can be clad with recycled white or blue membrane depending on the desired shading. It is attached to the circular nodes and serves only a filling function without contributing to structural stability. It provides shade and bears climatic loads over a span of up to 6 meters, which is much shorter than in its primary use. The cable net then transfers the loads to the arches.
The thrusts from the arches are absorbed by massive abutments: the connections at the upper node of the cladding supports. Bags made from membrane scraps and weighted with vegetated soil help counteract any potential uplift of the arches depending on the loading conditions.
