  1. Three circumstances on the geometric non - linear analysis are considered : the sag phenomenon of cables the nonlinear behavior of bending members and the geometry change due to large displacement. the non - linear behavior of cables is verified by introduced the ernst cable modulus of elasticity and cr formation is applied to analyze the non - linear of beams. an incremental - iterative method based on the newton - raphson method is adopted here to solve the non - behavior equations

    幾何非線性分析主要考慮三個方面：索的垂度效應、樑柱效應和結構大位移，其中：索的非線性分析採用ernst彈性模量對索材料的彈性模量進行修正，計及索的垂度效應的方法；梁單元的非線性分析採用cr列式法，計算中採用基於newton - raphson法的增量迭代方法求解非線性方程組。
  2. In order to obtain elastic stiffness matrices and geometry stiffness matrices that do not depend on subdivision of the element for convergence, the displacement functions are expressed in terms of the geometry properties of the section and this consideration leads to the formulation of exact stiffness matrices for linear elastic analysis given in this paper

    本文利用有限元方法對變截面梁單元進行研究。為了得到精度不依賴于劃分單元數目多少的彈性、幾何剛度矩陣，本文採用變截面構件幾何特性積分所獲得的軸向、側向位移函數。
