梁腹板偏心孔强度校核方法研究

Research on Strength Check Method of Eccentric Hole on Spar Web

主要对梁腹板偏心孔的强度校核方法进行了详细分析,并进一步探讨了按开孔上、下部位剩余腹板高度的比值来分配腹板剪力的理论基础,同时,还对梁腹板偏心孔的强度校核方法提出了改进意见。

This paper presents a detailed analysis on strength check method of eccentric hole on spar web and further discusses the theoretical basis of shear force distribution on web according to the ratio of the residual web height both above and below the hole. It also provides proposals how to improve strength check method of eccentric hole on spar web.
