摘要
采用结构通用程序ＳＡＰ５对焊接空心球节点进行有限元计算和分析，对７２种不同几何尺寸的节点进行了计算，其结果表明，轴力柔度系数ｆ和弯曲刚度Ｋｅ随球径、管径、球厚呈有归律的变化。通过回归分析，建立了轴力柔度系数ｆ和弯曲刚度Ｋｅ的计算公式。
In this paper, the welded hollow spherical joints are analysed and computed by finite elenent apprkach with SAP5program, Joints of 72 kinds different geomertical sixes are computed, their results show that the axial flsxibility coefficient f and flezural stiffness Ke are changing due to different jointe diameter、members diameter and walls thickness, Calculated formulae of the axial flexibility coefficient f and flexural stiffness Ke are attained by regnession analysis.
