摘　　要：钢结构网架在未来有着广阔的发展空间,其具有许多优点,尤其是螺栓球节点网架,但其节点仍存在缺点,利用有限元软件 ANSYS 对螺栓球节点网架进行不同尺寸偏心设计分析,比较不同偏心后对网架各杆件影响是否符合工程应用,对以后螺栓球网架节点优化设计在工程中应用打下了基础。Steel structure grid structures has very widest develop space by and by. it has many strongpoint, especially, the bolt globe grid structures has more strongpoint, but it＇s node has some demerit. Using Finite element software ANSYS analyse the bolt globe node grid that has dissimilarity eccentricity, Copare the dissimilarity eccentricity with not eccentricity is accord with engineering application. It lay foundation of using in the engineering by bolt globe grid structures node optimize design.

关 键 词：螺栓球节点 有限元方法 偏心设计
