Ingalls Rink
Ingalls Rink, or in full, David S. Ingalls Rink, is a hockey rink designed by architect Eero Saarinen and built between 1953 and 1959 for Yale University. Commonly referred to as "the whale," because of its appearance, the rink stands at the intersection of Prospect and Sachem Streets. The building was constructed for $1.5 million, which was double its original cost estimate. It seats 3,486 fans and has a maximum ceiling height of 23 meters.
Structural system
It employs an innovative structural system where a 90 meter reinforced concrete arch, from which a cable net is hung, supporting a timber roof. This causes a stable, double curvature form, though several cable ties were later added to the exterior of the building, linking the arch directly to the outer edges of the roof. Fred N. Severud was the structural engineer for the project.
Renovations
The Ingalls Rink was renovated at a cost of $1.5 million in 1991, when a new concrete refrigerant slab was added. The locker rooms were also refurbished.
