THEORETICAL ANALYSIS AND COMPUTATIONAL METHOD FOR NON-UNIFORM TORSION OF THIN-WALLED SPATIAL HELICOID GIRDERS(PART Ⅰ: FUNDAMENTAL THEORY)

  • 摘要: 本文应用矢量运算及薄壁曲线梁翘曲扭转理论,建立了空间螺旋形的薄壁曲线梁基本微分方程,用初参数法解出翘曲扭转微分方程,为进一步进行薄壁螺旋曲线梁的空间结构分析提供理论基础。

     

    Abstract: in this paper, based on the vector analysis and the warping torsion theory of curved thin-walled girders, a set of governing differential equations for the non-uniform torsion of thinwalled spatial helicoid girders is developed. The method of initial parameters is employed to solve for the bimoment B. The present theory. lays down the foundation for further analysis of thinwalled spatial helicoid girders.
