摘　　要：基于日本型钢手册中的蜂窝梁强度简化计算式,推导考虑塑性发展的强度计算式。通过非线性有限元分析与两根等比例试件的破坏荷载试验对比,以及与日本和前苏联相关计算式对比,说明其合理性,为工程应用提供参考。Based on the simplified strength formula of castellated beams in Japan＇s profile steel manual,this paper gave a new formula considering the plastic development of castellated beams.Then comparing it with the corresponding formulas offered by Japan and the former Soviet Union,two experiments were made and the FEA analysis was used to prove its rationality,which could provide a better reference for the project.

关 键 词：蜂窝梁 强度 塑性 有限元 试验
