摘　　要：应用三维非线性有限元方法,结合实际工程,计算了冷凝汽器支架典型钢结构节点在设计荷载、屈服荷载和破坏荷载作用下的应力、应变状况,分析了节点杆件和节点域的承载力随荷载步的变化关系,可为钢结构节点设计提供参考。Based on a practical engineering example,3D no-liner FEM is used to study the stress-strain condition of typical joint in the air-cooled condenser structure under design load,yield load and failure load.The relationship between the bearing capacity of joint members and joint region and variation of load step are analyzed.The results can be used as a reference for design of steel structure joints.
