摘　　要：研究加筋壁板在轴向压缩载荷作用下长桁凸缘的侧向稳定性。结合加筋壁板强度和刚度设计因素,对长桁凸缘的侧向屈曲临界载荷进行分析,并提出长桁支撑件的刚度设计指标计算方法,为工程设计人员提供指导以提高设计效率。The lateral stability of stringer flange of stiffened panel under axial compressive loading was studied. Combined the design factor of strength and stiffness of stiffened panel,the lateral buckling critical load of stringer flange was analyzed, and the calculation method of stiffness design criterion of support sheet of stringer flange was proposed. The method can provide some guidance for the engineering designers to improve the design efficiency.
