对变截面柱节点包钢加固的设计方法及施工技术进行了研究,提出一种先进的变截面柱节点加固方法,最后根据实际工程应用,论述该方法可行性。此方法是在变截面柱节点的柱交接处,设置一厚钢板,并在此钢板上打化学螺栓。以此钢板连接上下的加固角钢。研究结果表明,此加固方法显著的提高变截面柱节点的承载能力,同时提高施工速度,缩减工期。

The design method and construction technology of steel-clad reinforcement for variable cross-section column nodes are studied,and an advanced method for reinforcement of variable cross-section column nodes is proposed.Finally,the feasibility of this method is dis‐cussed based on actual engineering applications.This method is to install a thick steel plate at the joint of the column nodes of the variable cross-section column node,and bolt the steel plate with chemical bolts.Connect the upper and lower reinforcement angles with this steel plate.The research results show that this reinforcement method significantly improves the load-bearing capacity of the variable cross-section column joints,and at the same time increases the construction speed and reduces the construction period.
