摘要
在介绍防撞梁设计原则、过卷荷载取值的基础上，着重论述了偏心受力防撞梁设计问题．将薄壁杆件约束扭转理论运用于防撞梁内力及应力分析，推导出了简化形式的内力计算公式，给出了供设计使用的β，γ数表．最后，讨论了避免失稳、限制作用偏心及连结方式问题．
Based on the introduction to the design principle and overwind load determination of bumping beams. The design of bumping beams under eccentric force is discussed emphatically. The restrained twisting theory of thin wall rods is applied to the internal force and stress analyses of bumping beams. The simplified formulas calculating the internal force are derived and the numerical table of β and γ for design purpose is given. Finally the problems of the stabilization, eccentricity and connection type are discussed.
