钢筋断后伸长率检测数据

数据用途和场景：钢筋断后伸长率检测能够反应各个项目中钢筋断后伸长率是否符合规范，在钢筋质量上进行把控，对相关工程的安全性上具有积极意义。钢筋断后伸长率计算公式：断后伸长率=（断后标距-原始标距）/原始标距；标距单位为mm；每个不同规格的钢筋断后伸长率标准都不同，将以上数据以GB/T 1499.2-2018标准计算，计算后与标准的性能指标对比判断是否合格。

Data Purpose and Application Scenarios: The detection of the percentage elongation after fracture of steel rebars is used to verify whether the percentage elongation after fracture of rebars in various projects meets the specifications, control the quality of steel rebars, and has positive significance for the safety of relevant engineering works. The calculation formula for the percentage elongation after fracture of steel rebars is: Percentage elongation after fracture = (Gauge length after fracture - Original gauge length) / Original gauge length; the unit of gauge length is mm. The allowable percentage elongation after fracture varies for steel rebars of different specifications. The above data shall be calculated in accordance with the GB/T 1499.2-2018 standard, and then compared with the standard performance indicators to determine whether the rebars are qualified.
