다중 판별 분석을 통한 초고층 바닥판 거푸집 선정 모델

A proper formwork selection has important effects on the quality, duration, and cost of construction work. However, the selection method of a formwork systems are determined by a construction engineer or manager of the contractor's organization based on limited experience. Therefore, this study proposed to help a reasonable decision-making procedure of formwork selection using a discriminant analysis. In order to develop the model, we collected the historical data of 79 projects of cast-in-placed reinforced concrete structure above 30-story high-rise building in Korea. The factors affecting the slabform selection were chosen by an interview with experts, those are the number of stories, height of story, square meter of typical floor, shape of plane, and structure type. The systems were classified into aluminum form, sky-deck, table form, and conventional wood system. To verify suggested model, we tested the model using 10 data. As a result, 9 of 10 were classified correctly. Thus, selection model using a discriminant analysis would select a slabform efficiently.
