摘要
按照空间桁架模型，充分考虑了服役井架结构的几何非线性和材料非线性，研究了承载力计算方法，为深入研究服役井架结构的安全度和可靠度评定提供了结构分析基础。
On the basis of spatial truss model, both the geometrical and the material nonlinearities of the structure of a rig derrick under working conditions are fully taken into account,and the derrick load capacity is studied.A basis of structural analysis is provided for indepth studies on safety and reliability assessment of the structure of a rig derrick under working conditions.
