Study on Mock-up Construction Example of Free-Form Building Facade using External UHPC Panels - Focused on the Construction of Busan Opera House -

UHPC 외장패널을 활용한 비정형건축물 외장패널의 목업 시공사례에 대한 연구 - 부산 오페라 하우스 신축 공사 -

In the case of the Busan North Port, where the Busan Opera House is located, it is an environment exposed to various external deterioration factors such as frequent strong winds, seawater and salty winds, and an exterior material using UHPC (Ultra High Performance Concrete), a highly durable exterior material as a solution to this. Has been adopted. in this study, an economical production and construction direction was reviewed by applying UHPC to the exterior panels of atypical buildings that cannot cope with GFRC, metal, and glass, which are the main exterior finishing materials applied so far. When steel fibers are used, structural performance may be better than organic fibers, but due to environmental factors in Busan, corrosion due to exposure to steel fibers or problems with safety management after construction and completion may occur. Therefore, the site used the newly developed SACF fiber. Facade design of atypical buildings, which will increase in the future, is an important part, and the scope of use of UHPC panels is expected to increase in the future as design trends and demand for high durability increase.
