Abstract
Yawaragi Mori No Stadium' is a building with a large membrane roof which consists of space truss steel frames. Arch shaped roof structure realizes wide spans of 147.5m at the maximum, 125m in general area, respectively. Space trusses are applied to the arch structure, considering buckling restraint against compressive force and assembly accuracy control at the construction stage. Structural design of the building was conducted by 'Parametric Design' method, which produced three-dimensional analysis model applying some parameters and functions. The method was highly effective for achieving both the low roof height and reasonable substructure, due to the optimization of the balance between the rise and the thrust force. To complete the building in an ultra-short period of 9.5 months (60% of normal construction period), besides getting consensus among designers, structural engineers and construction technicians about the complicated roof shape, improved efficiency of both design and construction should be needed.
