Abstract

Purpose: The majority of long-life housings in Korea are generally evaluated as wall structures, and there are no realities of apartments that use column-structures such as the flat-plate and rahmen structures. In order to secure the highest and highest grades of certification for long-life housing, a durable and flexible column structure must be applied. However, there is no evaluation of excellence or best due to the problem of rising initial construction costs. Therefore, many problems can occur when there is no basic data for structure construction of a column structure apartment. In this study, we demonstrated a column structure using a rahmen structure and a flat-plate structure, compared the productivity and process with a wall structure, and obtained basic data of a long-life housing using a column structure to be constructed in the future. Method: The productivity of Form work, rebar, and concrete for structure work was analyzed by monitoring building of each of the wall structure, the rahmen structure, and the flat plate structure. Through the work process analysis, it analyzes the further cycle-time of the pillar structure, and tries to analyze the work process. Result: As a result of the productivity analysis, it was found that the productivity of rebar and concrete was not difference as that of the wall structure, but the productivity of the Form work was lower than that of the wall structure. As a result of the process analysis, it was found that the wall-structured structure appeared for 8 days, the flat plate structure for 9 days, and the rahmen structure for 11 days.
