借助中心压杆弹塑性失稳的山雷 (Shanley)理论 ,利用静力平衡条件 ,针对桥梁结构中各型承压杆件在横桥向集中荷载作用下的梁 柱力学行为进行了建模分析 ,提出了横向临界力概念 ,探讨了横向集中荷载最不利作用位置的确定方法
With the help of the Shanley theory of elasto-plastic buckling of the center strut, the dynamic behaviors of beam-column under various transverse loads under concentrated load are modeled using static equilibrium conditions. , Put forward the concept of transverse critical force, discussed the method of determining the most unfavorable position of lateral concentrated load
