钢筋混凝土水平加腋偏心节点受剪承载力计算

通过5榀不同加腋宽度的钢筋混凝土框架梁柱偏心节点的试验研究,探讨了梁端水平加腋偏心节点在低周反复荷载下耗能能力和受力性能,提出了不同加腋宽度下节点核芯区受剪承载力的计算方法,并将试验值与计算值进行了比较,两者吻合较好。

Based on the test of five specimens of beam-column connections with modified beam width,the energy dissi-pation and mdchanical charcteristic of beam-column connections with modified enlarged beam width under reversed cyclic loading are analyzed.Formulas of shear strength of beam-column core re-fions with modified enlarfed beam width are proposed.The analyt-ical results are in good agreement with the test results.〔
