静定结构受力分析中约束力换算公式与二力杆的妙用1)

THE CONVERSION FORMULA OF CONSTRAINED FORCES AND THE TWO-FORCE BAR METHOD FOR FORCE ANALYSIS OF STATICALLY DETERMINATE STRUCTURE1)

    摘要
  • 摘要: 对于满足两刚片规则或三刚片规则的简单静定结构,可以证明,用平衡方程进行受力分析时,必可做到一个方程解一个未知力。本文在一个方程解一个未知力的基础上,进一步提出了约束力换算公式及二力杆转化思路,使静定结构的受力分析更加简化。

     

    Abstract: For a simple statically determinate structure, there is one equilibrium equation for one unknown force. On this basis, the constrained force conversion formula and the transformation idea of two-force bar are proposed to simplify the force analysis of statically determinate structures.
