摘　　要：基于应用性目的,在已有研究成果、试验分析和工程经验基础上,分析高支模架结构的内在属性、单立杆和整架侧向的稳定问题;提出分级设计、选择铰接框架计算模型、按实际情况计算荷载、考虑材料初始缺陷影响、考虑结构重要性系数、注重细节、加强构造等设计建议;并提出以刚性单元体、刚性层和刚性面等构建几何不变杆件体结构体系、推行执业资格制度、保留一定安全冗余度、规范设计内容、改进创新高支模体系等安全策略。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.It’s 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.
