钢筋机械连接抗拉等级检测数据

数据用途和场景：钢筋机械连接抗拉强度检测能够反应各个项目中钢筋机械连接强度是否符合规范，在钢筋机械连接质量上进行把控，对相关工程的安全性上具有积极意义。钢筋机械连接抗拉强度检测判断公式A=（fo_mst-f_stk）/（fo_mst-1.25f_yk）*100；fo_mst为接头试件中钢筋抗拉强度实测值；f_stk为钢筋抗拉强度标准值；f_yk为钢筋屈服强度标准值；A为实测值与屈服标准值差比值；用JGJ 107-2016标准计算判定机械连接等级，用以上数据计算出结果后判断材料等级是否合格。

Data Purpose and Application Scenarios: Tensile strength testing of reinforcing bar mechanical connections can verify whether the tensile strength of such connections in various projects complies with relevant specifications, control the quality of reinforcing bar mechanical connections, and play a positive role in ensuring the safety of relevant engineering projects. The judgment formula for tensile strength testing of reinforcing bar mechanical connections is: A = (fo_mst - f_stk) / (fo_mst - 1.25*f_yk) * 100; where fo_mst is the measured tensile strength of the reinforcing bar in the joint specimen, f_stk is the specified tensile strength value of the reinforcing bar, f_yk is the specified yield strength value of the reinforcing bar, and A is the ratio obtained by dividing the difference between the measured tensile strength and the specified tensile strength value by the difference between the measured tensile strength and 1.25 times the specified yield strength value, then multiplying by 100. The mechanical connection grade shall be calculated and judged in accordance with the JGJ 107-2016 standard. After calculating the result using the above data, whether the material grade is qualified can be determined.
