环口板加固管节点是一种比较新颖的加固方法,施工方便快捷而且加固效果显著。运用有限元方法对平面内弯矩作用下的环口板加固 T 型圆钢管节点的极限承载力进行了研究。对环口板加固 T 型圆钢管节点的面内弯曲承载力进行了参数分析,参数包括支管直径与主管直径比β,主管直径与2倍主管壁厚的比γ,环口板厚度与主管管壁厚之比τc 和环口板长度与支管直径之比 lc/d1等计算。结果表明,采用适当尺寸的环口板加固后的 T 型管节点的承载力相对于未加固 T 型管节点的承载力得到显著提高。改变环口板的厚度相对于改变环口板的长度对静力强度的提高更有效。最后,在参数分析的基础上提出了环口板加强型 T 型圆钢管节点在平面内弯矩作用下的承载力计算公式。%Collar plate reinforcement is a new method for reinforcing tubular joints, and it is of fast fabrication and effective. Finite element method is used to investigate the static strength of collar plate reinforced circular hollow section (CHS) T-joints subjected to in-plane bending load. A study is conducted to analyze the effect of geometrical parameters, i.e. brace-to-chord diameter ratio β, collar-plate to chord wall thickness ratio τc, and collar-plate length to brace diameter ratio lc/d1, on the static strength of tubular T-joints. It is found that significant strength enhancement can be achieved for a collar plate reinforced tubular joint through suitable size design comparing with the un-reinforced one. Compared to the length of the collar plate, the thicknesses of the collar plate is more effective for improving the static strength of the T-joints. Finally, a parametric equation for predicting the load bearing capacity of circular tubular T-joints with collar plate reinforcement subjected to in-plane bending load is presented.
