摘　　要：分析了纸质杆系结构不同节点连接方式对结构强度的影响,明确了节点设计的要点,确定了简单杆系结构的最佳夹角,探索了不同节点形式下杆件的内力变化及结构质量变化情况,为工程中杆系结构节点简化带来的实际计算误差做参考。In this paper,the influence of the different types of joint on structural strength of bar system was analyzed. The principle of joint design and the best angle of triangular bar structure was also proposed. The change of internal forces and structure mass with different joint design was explored. Provide reference for the calculation error of bar system induced by simplified joint.
