THEORETICAL ANALYSIS AND COMPUTATIONAL METHOD FOR NON-UNIFORM TORSION OF THE THIN-WALLED SPATIAL HELICOID GIRDERS (PART 2 COMPUTATIONAL METHOD)

    摘要
  • 摘要: 本文在上文1所导出的空间螺旋形薄壁曲线箱梁约束扭转微分方程及其参数解的基础上,用能量理论求出该箱梁单元的刚度矩阵与等效节点力算法,编制了按照刚度法分析的程序。通过与国内外文献的比较,验证了本方法的可靠性。

     

    Abstract: In this paper, based on the fundamental theory of the foregoing paper1, a generalized three-dimensional element stiffness matrix of the thin-walled spatial helicoid girder and the corresponding equivalent nodal force vector subjected to uniformly distributed load have been developed by the principle of strain energy. Some numerical results have been compared with the reference 3 and reference 4 to identify it's credibility.
