摘要
垂直加劲肋节点适于柱截面较小的方钢管(矩形管)柱和H型钢梁节点。因此,采用有限元方法,以垂直加劲肋长度和高度为主要参数,对垂直加劲肋节点的承载力、刚度、应力分布和破坏模式进行了分析。研究表明:垂直加劲肋节点承载力、弹性刚度较大;垂直加劲肋长度对节点承载力和刚度都有贡献;加劲肋高度只对节点刚度有影响。最后提出了加劲肋设计公式,供工程参考。
The vertical stiffener connection is suitable for rectangular steel tube column that the sectional area is smaller and H-steel beam connections. So by using finite-element method and taking the length and the height as main parameter, the bearing capacitY, stiffness, stress distribution and destruction pattern of the vertical stiffener are analyzed. The research has indicated： the bearing capacitY and elastic stiffness of the vertical stiffener is bigger; the length has do contribution both to the bearing capacitY and stiffness; the length just has influence on stiffness. In the end, the design to engineering. formula of stiffener is put forward which can supply reference
