摘　　要：波纹腹板梁是一种经济高效的新型梁结构形式。针对起重机主梁结构在力学性能、疲劳特性和经济性等方面的特殊要求,结合国内外的研究成果和相关规范,对波纹腹板用于起重机的可行性进行研究。提出了采用同等条件的波纹腹板主梁结构在弯曲强度和静刚度方面虽稍有不足,但在疲劳特性和经济性方面会有明显的优势,因此开发基于波纹腹板的起重机主梁结构是可行的。Girder with corrugated webs is a kind of new and economical structure. According to the special requirements on the mechanical performance, fatigue performance and economy, considering the recent research achievement and relative code, the feasibility of corrugated web based crane main girders was investigated. It showed that the bending strength and the static deflec- tion of the corrugated web girders are not better than that of fiat web girders, while the former has great advantages on fatigue be- havior and economy. Hence, it proposed that the access of girder with corrugated webs to cranes was feasible.
