摘　　要：整体翼梁支柱通常用来提高腹板剪切稳定性,支柱的强弱直接关系梁的初始剪切屈曲临界应力。为研究支柱刚度与梁腹板稳定性的关系,设计了4组不同参数的整体翼梁腹板剪切稳定性试验,通过试验与理论计算的对比分析,给出了一种可靠的整体翼梁支柱刚度计算方法,为整体翼梁设计及强度分析提供参考和指导。Integrally wing-beam strut were often used to improve shear stability of the web. The initial instability stress of the beam web was directly related to the strength of strut stiffness. For investigating the relationship between strut stiffness and web shear stability,four different structural parameters of integrally wing-beam web shear stability experiment were designed. By comparing the experiment and theoretical analysis,a reliable calculation method for the stiffness of integrally wing-beam strut was obtained,which can provide reference and guidance for the design and strength analysis of integrally wing-beam structure.
