摘　　要：根据简支梁刚度计算的基本原理,通过理论分析并结合有限元计算结果,对圆孔蜂窝梁挠度计算方法进行了探讨,提出圆孔蜂窝梁跨中的挠度计算公式,并给出了具体算例。同时,研究出影响梁挠度放大系数的各参数及其规律。实践证明,该计算方法和分析结果在工程设计中方便、精确、可行。Based on the basic principles of calculating the stiffness of a simply-supported beam, the ways of analyzing the deflections of the simply-supported castellated beams are studied. Combining the results Of FEM program, the formulas for calculating the deflections of the mid-span of beams are provided. Meanwhile, it is given that the parameters influencing the amplification factor of beam deflection and law. Some useful conclusions are drawn for reference in the structural design and research.
