为研究半刚性节点对JJ160/41-K型钻机井架极限承载能力的影响，采用零长度的双向变刚度螺旋弹簧来模拟井架构件焊接节点的半刚性，建立了半钢性井架结构的有限元模型。并通过钩载加载试验与计算机仿真分析，研究了半刚接节点对石油井架整体结构的应力、位移以及结构承载能力的影响。

Aiming at study the influence of load capacity with semi rigid connection to derrick structure of JJ160/41-K. Using spring element model with stiffness variation of double direction to simulation of the semi-rigid nodes, and the establishment a finite element model of derrick with semi-rigid connection. And through the load hook load test and computer simulation analysis, study semi-rigid nodes of influence in stress and displacement of the whole structure and ultimate of load capacity for oil derrick structure.
