【摘要】 本文参照梁与箱型截面柱强轴连接时的扩翼参数,设计了3组工型梁柱弱轴连接的斜边为直线的扩翼型节点模型,应用有限元软件ABAQUS分析了节点扩翼参数对扩翼型节点滞回性能的影响规律。研究发现:当钢材达到屈服强度后,扩翼段的外伸宽度、扩翼段斜边沿梁纵向长度、扩翼段斜边根部至蒙皮板间的距离对节点骨架曲线的影响程度依次减小;工字型梁柱弱轴连接的扩翼参数取值范围小于扩翼梁与箱型截面柱强轴连接时更加合理。更多还原

【Abstract】 Refering to parameters of widen flange box section with strong axis direction,three models are designed and those widen flange section type is straight line beveled edge. The finite element software ABAQUS is used to analyze the influence rule of widen flange section’s hysteretic behavior with different section parameters. When the steel element reaches the yield strength,the parameters’ degree of influence on joint skeleton curve decreases in turn such as the,outer width of the widen flange section,longitudinal length of the beveled edge of widen flange section and the distance from the root of the beveled edge of widen flange section to diaphragm skin. It is resonable that the range of widen flange section parameters in weak axis direction ’s connection of I-shaped beams and columns is less than the range of widen flange section parameters in stronge axis direction’s connection of boxsection column.更多还原
