摘　　要：本文对开口薄壁杆件采用薄壁杆件弯扭分析的一致理论,利用线性插值函数来描述构件的纵向翘曲位移和剪力滞后的影响,将缀板的作用视作对开口杆件的弹性支承,建立了杆件整体稳定分析的计算模型,求出问题的拉格朗日函数。从而得出对整体稳定性分析时的哈密顿方程。为带缀板的开口薄壁钢构件整体稳定性研究提供了一种新的思路。In this paper, the opening part of the thin - walled bar theory of consisten- cy, using linear interpolation function to describe the components of the longitudinal warping displacement and shear lag effect, the role of the bat- ten plates as elastic support on the open bar, established the calculation model of rod overall stability analysis, the problem for the Lagrange equa- tion. Thus the overall stability analysis of the Hamiltonian equation. With which provides a new idea of the overall stability of open thin - walled steel members of the board.
