| 摘 要： | 以大挠度理论为基础,考虑剪切变形的影响,对压杆的稳定性进行了分析,推导得出了组合压杆屈曲后的挠度与荷载关系的函数表达式.通过算例,说明利用该公式不仅能描述压杆屈曲后挠度曲线的形状,而且还能给出压杆屈曲后挠度值的大小,从而为精确分析压杆的极限承载力,提供了一种理论分析的方法.

| Abstract: | Based on the large deflection theory,the stability of compressed members with their shear deformation effect taken into consideration is studied.The postbuckling load deflection function of compressed built up members is deduced.With the examples,not only the postbuckling shape of deflection curve is described,but also the value of deflection of the compressed built up members is obtained.Thus this paper offers a theoretical method for accurate analyzing the ultimate load capacity of the compressed members. |
