The elastic modulus of steel bars refers to the stress-deformation relationship experienced when the steel bars undergo specific deformation under applied load. It is an important parameter for evaluating the elastic properties and hardness of structural members, and exerts a crucial impact on concrete components. This dataset can be used to perform safety evaluation on the qualified status of steel bar elastic modulus, providing reference and technical support for government supervision and consumer safety.
1. Data Collection: Collect information such as the names and types of steel bar samples;
2. Qualification Test for Elastic Modulus: Obtain corresponding elastic modulus test results by detecting the elastic modulus of steel bars. The elastic modulus X of steel bars is calculated as X=ρ/ε, where ρ is the density of the steel bar and ε is the strain of the steel bar;
3. Data Processing: Screen out the test results of problematic items of steel bar elastic modulus for evaluating the safety of steel bars. The standard value of steel bar elastic modulus is 200 GPa. By comparing X with the standard value, it is judged as qualified when X ≤ 200 GPa, and unqualified when X > 200 GPa. After testing, count the number of problematic test instances Y of steel bar elastic modulus, sum up the total number Z of all steel bar elastic modulus tests, and calculate the discovery rate M of problematic elastic modulus as M = Y/Z × 100%;
4. Data Application: The test results of problematic items of steel bar elastic modulus can be used as the basis for steel bar safety evaluation, providing technical support for regulatory authorities to carry out their supervision work.
