摘要
介绍 GB 50017—2003?钢结构设计规范?和 BS EN 1993-1-8∶2005?Eurocode 3：Design of Steel Struc-tures?中关于支管只承受轴力作用下 X 形、T 形(或 Y 形)和 K 形3种平面圆管相贯节点以及 TT 形、KK 形两种空间圆管相贯节点承载力计算公式。算例表明：GB 50017—2003中支管受拉时节点承载力大于支管受压时节点承载力,BS EN 1993-1-8∶2005中弦杆表面发生冲切破坏计算所得的节点承载力远大于弦杆表面发生塑性破坏计算所得的节点承载力,且按 BS EN 1993-1-8∶2005计算的节点承载力介于按 GB 50017—2003支管受拉时的节点承载力和支管受压时的节点承载力之间。
Abstract
ABSTRACT:The calculation formulas for the bearing capacity of three types of panel circular tubular joints under axial force(X-joint,T-joint or Y-joint and K-joint)as well as two types of spatial circular tubular joints (TT-joint and KK-joint)in Code for Design of Steel Structures (GB 5001 7—2003 )and Eurocode 3:Design of Steel Structures (BS EN 1 993-1-8∶2005 )were introduced.Combined with the examples,the results indicated that the bearing capacity of the joints under axial tension in GB 5001 7—2003 is higher than that under axial pressure,and according to BS EN 1 993-1-8∶2005,the bearing capacity of joints with punching shear failure on chord member surface is considerably greater than the joints with plastic failure on chord member surface.In addition,the bearing capacity of the joints based on BS EN 1 993-1-8∶2005 is between the axial tension for the brace members and the axial pressure for the brace members in GB 5001 7—2003.
