| 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. |
