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 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 frame was conducted for increasing the construction ability and reducing the lifting capacity. As a results, the resistance to lateral concrete pressure during pouring of concrete can be controlled by form-tie that connects the formwork, and accordingly, the span of the formwork or the cross-section of the horizontal member may 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.
