摘　　要：利用SAP2000软件的静力非线性分析方法(pushover)中自定义侧向力分布的功能,模拟钢丝绳的不断增加的拉力(最后达到断绳荷载),同时计算中考虑钢井架的几何及材料非线性,求得钢井架的极限承载力;建立钢井架在钢丝绳拉力作用下的荷载-位移(杆件内力)曲线,为钢井架优化设计提供帮助。The self defined side force distribution function of the static nonlinear analysis method with the SAP 2000 software was applied to simulate the continuously increased pulling（until reached to the broke rope loading） of the steel rope.Meanwhile the geometry and the material nonlinear of the mine shaft steel headframe shall be considered in the calculation and thus the ultimate loading capacity of the steel headframe could be obtained.The load-displacement（inner force of the bar） curve of the steel headframe under the role of the steel rope in pulling was established and could provide the references to the optimized design of the mine shaft steel headframe.
