摘要: 针对框排架结构中通常存在变梁变柱异型节点的实际,在节点试验研究及整体结构试验结果的基础上,研究了该类异型节点的破坏机理,提出了该类异型节点的抗剪承载力计算公式和节点区的加强构造措施,为该类异型节点的合理设计提供依据。Abstract: The R. C. frame-bent structures commonly contain abnormal joints. Based on the experimental result, the damage mechanism and the failure of abnormal joints under the shear force are analyzed. According to experimental result, the formula for calculation of the shear-bearing capacity of abnormal joints and the method for strengthening the abnormal joints are given, which provides a basis for rational design of the abnormal joints.
