Case Study of Precast Concrete Erection Work of the Heavy-Loaded Long Span Structure

초대형 건축물의 PC부재 양중작업 사례연구

Along with the logistics development, heavy-loaded warehouses and sales facilities tend to be bigger and designed as a PC structures. PC erection work of heavy-loaded structures is influenced by various factors, including the required construction duration, site and surrounding situations, safety, PC member procurement, equipment rental cost, which ultimately impact the construction cost. It requires creative efforts and a lot of time when preparing an erection plan in consideration of these factors, and the plan prepared has a great influence on safety as well as the construction duration and cost. However, many engineers do not have enough experiences on PC erection work of heavy-loaded, long span structures, making it difficult for them to set erection plans and establish simulations. The study's results will provide a knowledge to obtain a solution for engineers to establish PC erection plans of heavy-loaded, long span structures.
