This design study showcases long-span roofing solutions for a resort complex, highlighting challenges and construction methods.
Inspire Resort, located in Yeongjong-do, Incheon, is a large-scale integrated complex with a total gross floor area of approximately 348,000 m2. This study summarizes the structural design of the project’s long-span roof systems, focusing on the Pool Dome and Arena roofs. The Pool Dome employs radially arranged one-way steel trusses with ring trusses spanning 74.6 m, while the Arena roof employs arched one-way steel trusses spanning 95.8 m. This paper presents the design considerations, including realistic loading scenarios, boundary details, and key considerations for fabrication and erection of the long-span roof truss systems of the Pool Dome and Arena.
