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。
Through the low-frequency reciprocating test of six nodes in the middle of the 1: 2 ratio Z-shaped concrete columns, the failure form of the Z-shaped columns was obtained and the ultimate shear capacity of the core in the frame was measured. The formulas of the relevant codes are used to calculate the calculated value of the shear strength of the core of the node. The comparative analysis between the experimental value and the calculated value of the test results shows that the deviation of the shear strength of the core of the Z- The conclusions can provide reference for the design and calculation of practical engineering Z-section concrete columns.
