支撑框架体系在国内规范中介绍甚少,各设计应用单位和加工单位对该体系的理解各不相同,导致加工与设计意图实际不相符合,作为系列论文之一,以我国两阶段设计方法为基础,详细介绍钢结构支撑框架体系柱拼接设计方法,供设计人员和加工单位参考. The supporting frame system is rarely described in the domestic norms. The design and application units and the processing units have different understanding of the system, resulting in the fact that the processing and design intent do not actually meet the requirements. As one of the series of papers, taking the two-stage design method in our country as Basis, detailing steel structure support frame system column splicing design method, for designers and processing units for reference.
