Application of Double-skinned Composite Wall System to Improve Efficiency of Retaining Wall Construction
초록
영어
The construction of a basement floor utilizes reinforced concrete (RC) structures composed mainly of rebar work and form work. RC structures lower construction efficiency and significantly delay the construction because they require a large number of temporary materials and wooden formwork. In this study, a Double-skinned composite wall (DSCW) System was developed to improve the efficiency of retaining wall construction. DSCW is a precast concrete (PC) wall in which two thin concrete panels are connected parallel to each other with truss-shaped reinforcement between them. DSCW can contribute to securing integrity, reducing the delay in construction. An overall process for the member design and construction stage of the DSCW system was proposed, and its improvement effects were examined regarding various aspects in comparison to the RC method.
