摘要
基于8个钢筋混凝土框架异型节点的试验,分析了异型节点的初裂与常规节点的不同之处。在分析钢筋混凝土框架异型节点受力的基础上,得出了异型节点的初裂承载能力取决于异型节点"小核芯"的结论,并以"小核芯"为基本计算单元,提出了钢筋混凝土框架异型节点的抗裂承载能力计算公式。
On the basis of experiment of 8 abnormal joints of reinforced concrete frame,the anti-crack properties of the abnormal joints and normal joints are discussed.According to the analyses of the working mechanism of the abnormal joints,the paper proposes that the anti-crack capacities mainly depend on the minor core of the abnormal joints.After analysis of the anti-crack properties of minor core,the formula of the anti-crack capacity of the abnormal joints is put forward.
