Sports and Recreation Hall in Takamatsu/Japan
1. The load of the concrete structure rests on four reinforced concrete columns, which are arranged and designed in such a way that the torsional stresses generated by the suspended roof are absorbed by the edge beams. Each pair of column foundations is connected to each other by a concrete sill. 2. The sloping spectator stands (37 m wide at the bottom, 18 m at the top) rest on concrete support grids; they transition into the grid-like concrete floor of the arena area.
