Development of auto-climbing formwork system for composite core walls
This study was conducted to develop a corner-supported auto-climbing formwork system (CS-ACS) that uses steel plates installed at the corners as support points in connection with the development of a steel-concrete composite core-wall structural system. For the optimal design of the CS-ACS, a numerical study using FE approach was conducted on the concrete lateral pressure acting on the form during construction and the wind load that may occur when the formwork is lifted. Through the foregoing, each constituent member of the system was optimally designed and displacement and stress calculation equations that can be used for design were proposed. For the lateral pressure of concrete, an analytical study was conducted with about 400 variables, and for the effect of wind load, a study was conducted with 50 variables so that the members can be optimally designed. Through the study, it was found that the CS-ACS is more advantageous than the existing cantilever type ACS for structural stability, displacement, and stress control because it can form a formwork system as a simply supported flexural member using the preinstalled end steel plates as support points and can reduce the burden of lifting as the unit weight of the system can be designed at a level that is half of that of the existing ACS.
