重型承插型盘扣式钢管脚手架连接节点对脚手架的稳定性影响很大.对此,首先对重型承插型盘扣式钢管脚手架连接节点在半刚性理论基础上进行有限元建模并加以分析,然后通过试验所得出的弯矩-转角曲线与有限元模拟得到的弯矩-转角曲线进行对比,从而检验有限元分析的可靠性.对影响节点抗弯性能的连接盘厚度、插销材料本构、插销厚度及插入深度 4 种参数进行单一随机有限元分析,为后续研究多种随机缺陷共同随机耦合作用对节点稳定性的影响奠定基础.
Bending Performance of Heavy-duty Socket-type Disk Lock Steel Tubular Scaffold Connection Joints
The connection joints of heavy-duty socket-type disc lock steel tubular scaffold have a great influence on the stability of scaffold.In this regard,firstly,the finite element modeling and analysis of the connection joints of heavy-duty socket-type disc lock steel tubular scaffold are carried out on the basis of semi-rigid theory,and then the bending moment-rotation curve obtained by the test is compared with the bending moment-rotation curve obtained by the finite element simulation,so as to test the reliability of the finite element analysis.The single random finite element analysis is carried out on the four parameters of the thickness of the connecting plate,the constitutive of the bolt material,the thickness of the bolt and the insertion depth,which affect the bending performance of the joint,whick lays a foundation for the follow-up study of the influence of the random coupling of various random defects on the stability of the joint.
