코너강판벽을 활용한 개량형 자동인양 거푸집 시스템 최적 설계 = Optimum Structural Design of Modified Automatic Formwork System Using Corner Steel Plate Walls

다국어 초록 (Multilingual Abstract)

In this study, an analytical study was conducted on the optimum structural design of modified auto climbing formwork system that utilizes the steel plates at both ends of the core as a support point in connection with the corner steel composite core wall structural system. Accordingly, data of optimal design of system components are accumulated through variable studies on the geometrical parameters such as the span and height of the formwork system and the spacing of the horizontal members and form-ties. And weight analysis of the total formwork frame was conducted for increasing the construction ability and reducing the lifting capacity and loads acting on anchor bolts. As a results, the resistance to lateral concrete pressure during pouring of concrete can be controlled by form-tie that connects the both-sided formwork, and the span of the formwork or the cross-section of the horizontal member not significantly affect the design of the constituent member. And, the equations for expecting the maximum displacement of
formwork and the maximum stress of the form-tie were proposed for designing formwork in various conditions.
