Design and Construction of the 85 m Cantilever Roof: Busan Cinema Centre, Korea

摘要

This paper discusses the design and construction processes of the 85 m cantilever roof of Busan Cinema Centre. It introduces the project with a brief description and focuses on the structural challenges faced by the engineers during the design and construction phases while resolving issues regarding the cantilever. As the 85 m cantilever with the demanding architectural geometry is a nonconventional structure, the design challenges faced were to establish sensible loads for the structure and to find a reasonable workflow to deal, exchange, and analyse the desired geometry in cooperation with the design architects. The cantilever structure was lifted up to the designed level by jacks on top of four temporary masts combined with the conventional shoring method. The building was completed in October 2011 for the Busan International Film Festival 2011 in Busan, Korea.
