钢筋混凝土框架节点是指框架梁柱交接点 ,也称节点核芯区。震害调查表明 ,框架结构的震害多发生在柱和梁柱节点核芯区［１］,框架节点破坏的主要形式是节点核芯区剪切破坏和钢筋锚固破坏 ,严重的会引起整个框架的倒毁 ,且节点破坏后的修复也比较困难 ,因此 ,设计规范 ［２］［? Reinforced concrete frame node refers to the frame beam junction, also known as the node core area. The seismic damage investigation shows that the seismic damage of the frame structure mostly occurs in the core region of the column and beam-column nodes [1]. The main form of the failure of the frame node is the shear failure of the core region of the node and the anchoring failure of the reinforcement, which seriously causes the entire framework The destruction of the node and the destruction of the node is also more difficult, so the design specification [2]
