钢筋混凝土扁梁边节点钢筋粘结锚固性能试验研究

Study on bar bond and anchorage performance test of edge joints for reinforced concrete floor flat beams

通过对钢筋混凝土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边节点破坏机制、钢筋粘结锚固性能,突破了《建筑抗震设计规范》对扁梁截面宽度限值的要求,验证了现有的钢筋混凝土扁梁边节点设计方法的正确性,为钢筋混凝土扁梁边节点钢筋粘结锚固性能及工程应用提供了参考依据。

Performance on failure mechanism,bearing capacity,rupture forms and bar bond and anchorage performance of edge joints for which there are three different width height ratios is contrasted and analyzed in this paper through loading test with reinforced concrete flat beams.Requirements for section width limit of flat beams in code for seismic design of buildings are made a breakthrough,validity of the existing design methods for edge joints is demonstrated for reinforced concrete flat beams.A gist is provided for design methods and engineering application of edge joints for reinforced concrete flat beams.
