摘要: 通过对钢筋混凝土有边梁扁梁边节点加载试验，对比分析了扁梁宽度与柱宽三种不同比值的扁梁端部节点破坏机制，承载力、变形、裂缝和破坏形态等受力特性，验证了现有的钢筋混凝土扁梁节点设计方法的正确性，同时突破了《建筑抗震设计规范》(GB50011-2001)对扁梁截面宽度限值的要求，为钢筋混凝土扁梁节点设计方法及工程应用提供了科学依据。

Abstract: Failure mechanism, bearing capacity, deformation and rupture forms etc of edge joints for which there are three different width height ratios are contrasted and analyzed through loading test with and without reinforced concrete flast beams. Validity of the existing design methods for edge joints is demonstrated for reinforced concrete flat beams. A breakthrough is made at the requirements for section width limit of flat beams in Code for Seismic Design of Buildings (GB 50011-2001)and a scientific basis is provided for design methods and engineering application of edge joints for reinforced concrete flat beams.
