Abstract: For application purposes,based on the existing research results and experimental analysis and engineering experience,it was analyzed the high formwork support inner properties,lateral stability of single upright stanchion and the entire system.Hierarchical design,selecting the hinged framework support calculation model,calculated according to the actual load were put forward.The material coefficient impacted by the initial flaw and the importance coefficient of structures were presented.Its also proposed safety strategies,such as construction of invariable structure system of geometric member by building rigid unit structure and rigid layer and the rigid surface,promoting acceptance qualification certificate systems,retaining redundant degree security and improving high formwork supporting system etc.
