中文摘要:
      针对传统承插型盘扣式钢管支架在实际应用中存在的问题,优化设计了一种新型全工况适应型盘扣式钢管支架体系。为检验新型体系的安全稳定性,对螺丝盘节点受力性能进行了基本单元体试验研究和节点半刚性有限元分析,然后对该基本单元体进行SAP2000建模分析,通过对比分析试验值和理论值,验证有限元分析及试验结果的合理性,确定节点刚度值的取值范围。研究结果表明:螺丝盘与丝杆连接可靠,节点不会先于构件发生破坏;节点刚度值是影响结构稳定承载力的重要因素,建议在工程应用中,半刚性节点的刚度值取70 kN·m/rad。
英文摘要:
      The optimized design of a new full-work condition adaptive steel pipe scaffold system was proposed to improve the limitations of traditional socket-type disc button steel scaffolds in practical application. In order to test the safety and stability of the new system, the basic unit body test and the semi-rigid finite element analysis of the steel pipe scaffold joints were carried out. Then, a SAP2000 modeling analysis was performed out on the basic element, and the rationality of the finite element analysis and test results was verified by comparing the experimental and theoretical values, and the range of the stiffness value of the joints was determined. The results show that the connection between the screw plate and the screw rod is reliable, and the joints will not be damaged before the component failure. The stiffness value of the joint is an important factor that affects the stability of the structure. It is suggested that the stiffness value K of the semi-rigid joint should be taken as 70 kN·m/rad.
