摘　　要：通过设计6个半刚接钢框架-方钢管龙骨隔墙试件,并对其进行低周往复加载,得到滞回曲线及骨架曲线。分析各个试件的破坏过程、承载能力、抗侧刚度、延性和耗能能力,研究该结构体系的抗侧力性能。结果表明:适当减小方钢管间距可以提高结构的承载能力、抗侧刚度和耗能能力;增大方钢管截面尺寸可以显著提高结构的承载能力;OSB板对结构的承载能力和抗侧刚度贡献很大,而结构的耗能能力和延性主要由半刚接钢框架和方钢管骨架提供。根据刚度叠加原理,提出结构抗侧刚度简化计算式。The hysteretic tests of six semi-rigid steel frames with square steel tube keel wall specimens were carried out, and the hysteretic curves and skeleton curves were obtained. The failure process, bearing capacity, lateral stiffness, ductility and energy dissipation capacity of each specimen were analyzed. The lateral force resistance behavior of this kind of structure system was discussed. The research results showed that reducing the spacing of square steel tubes could improve the bearing capacity, lateral stiffness and energy dissipation capacity of the structure system. Increasing the section size of square steel tubes could significantly improve the bearing capacity. OSB overlaid boards contributed greatly to bearing capacity and lateral stiffness, while the energy dissipation capacity and ductility were mainly provided by semi-rigid steel frame and square steel tubes. A simplified formula for calculating lateral stiffness of the structure system was proposed according to the stiffness superposition principle.
