【摘要】 对螺栓角钢钢节点半刚性连接采用非线性有限元分析方法 ,对连接中的主要构件的顶部、底部、腹板角钢、高强螺栓、梁翼缘、柱翼缘和柱翼缘加劲肋进行三维非线性有限元精细模拟 ,针对有无柱加劲肋、有无腹板角钢等几种连接的情况进行比较分析 ,探讨了螺栓角钢半刚性连接的受力性能。更多还原

【Abstract】 The present study describes a 3D nonlinear analysis for semi rigid connections of bolted angle The bolts,top and bottom angles,web angles,column flange,beam flange and contact of connections are molded finely with 3D nonlinear finite element Through comparing and analyzing different types and cross sections of connections,some conclusions about the forced behavior of semi rigid connections of welded angle are drawn at the end of the paper更多还原
