Steel elements exhibit varying characteristics during site installation after shop manufacturing. There may be a mix-up owing to unclear management methods for transport, and deformation might occur during field installation. Moreover, the technical basis for evaluating repair methods is narrow. In this study, variations in material properties after performing mechanical calibration were determined for widely used steel types, such as SS400 and SM490, in which thicknesses of 30 mm and less are frequently used on sites. The test results showed that the mechanical calibration in unheated and thermal heating cases increased the yield strength and tensile strength of steel, and the Korea Standard value was satisfied. A yield ratio of approximately 85% or less was obtained, indicating sufficient toughness. In addition, variations owing to thermal heating did not occur when temperatures below 650 °C were applied.
