中文摘要：

利用正交试验设计法和现行规范方法对影响现浇钢筋混凝土框架外节点抗剪承载力的各因素进行分析，考虑的主要因素包括轴压比、混凝土强度等级、竖向钢筋屈服强度。框架外节点抗剪承载力对混凝土强度等级这个因子最为敏感，轴压比次之，竖向钢筋屈服强度影响最小。随着混凝土强度等级的提高、轴压比增大，节点抗剪承载力相应增加，曲线呈上升趋势，随着竖向钢筋屈服强度的提高，梁柱外节点抗剪承载力变化不明显。为以后现浇钢筋混凝土框架外节点抗剪承载力的试验、设计和施工提供基本依据。

英文摘要：

Shear strength of exterior reinforced concrete frame joint is analyzed with orthographic design method and code method, and the chief factors reviewed include the axial compression ratio, the concrete strength grade and yield strength of vertical reinforce. The strength of concrete is the most important factor affecting the shear strength of component, next to axial-compression ratio and the minimum factor is the yield strength of vertical reinforce. Shear strength of exterior reinforces concrete frame joint increase with the enlargement of the axial compression ratio, the concrete strength grade, and is not obvious with yield strength of vertical reinforce. The purpose of the research would be used in test, design and construction of the exterior reinforced concrete frame joint.
