Concept

Three tram canopies were designed and built as a part of the tram construction in the city Sapporo. The existing tramways were renovated to construct a closed loop which gives more convenience and liveliness to the shopping street in front of the main station. The new tramways have reserved space for tram cars in traffic roads. The new tram canopies measure 3m high, 3m wide for a length of 25 and 27.5m respectively. The architectural challenge was to provide smooth flows from the pedestrian paths to the tram rails, with protections against wind and snow. It was resolved in the plan arrangement of the canopy that prompts pedestrians to walk into the interior space. The interior spaces are supported by three side walls across the 27.5m length that are positioned closely to the tram way at the edges and to the pedestrian way in the middle. They are provided with a large glass aperture in between the walls for the wind protection, which creates high spatial quality. Using custom sandwich steel panels as a structure realizes clarity and seamlessness in its appearance while accommodating necessary facilities. In this way, the canopies have achieved a sculptural form with simplicity and presence.

Specific features

Each canopy comprises of sandwich-structured components made of 6mm thickness SS400 steel. It varies in depth from 250mm to 300mm for both the wall and the roof part, with internal transverse stiffeners. The sandwich components are fabricated from sheets of steel panels that were plug-welded, finished with grinding, forming closed boxes. This components allows the walls and the roofs to perform as a continuous rigid structure. The panels were arranged to have equivalent stiffness to comply with the seismic criteria in the Japanese codes.
