| 摘 要： | 通过6个1∶2比例的Z形截面混凝土柱框架中间层中节点的低周往复试验,得到Z形柱框架节点的破坏形态,测得框架节点核心区极限抗剪承载力试验值,并利用现行相关规范给出的公式计算节点核心区受剪承载力的验算值,把试验值与规范验算值进行比较分析,得出采用现行规范计算Z形框架柱节点核心区抗剪承载力的偏差,所得结论可为实际工程Z形截面混凝土柱设计计算提供参考。

| Abstract: | Under low cyclic loading,6 interior frame nodes of Z-shaped concrete columns with 1/2 scale were tested.The fracture morphology of frame nodes of Z-shaped columns was obtained.The limits of shear capacity of frame node core zone were measured,and the check values of shear capacity of node core zone were calculated by the formulas in current related standards.Through the analysis of comparison between test values and standard calculation values,the deviations of shear capacity of node core zone of Z-shaped columns calculated by current standard were obtained.The conclusion may be a reference for the design and calculation of Z-shaped concrete columns in practical projects. |
