| Abstract: | Samples of Q235 and Q345 steel, extracted from hot-rolled products destined for building structures, were subjected to measurement via the Brinell hardness approach in controlled laboratory conditions and on-site applications. The parameters, including Brinell hardness, yield strength, and tensile strength, were assessed using a specialized instrument known as the portable Brinell hardness test apparatus (PBHTA). A meticulous comparison between readings obtained through PBHTA and those acquired with standard laboratory equipment revealed a discrepancy margin confined within 1.5% relative to the HBW1/30 Brinell hardness benchmark. Subsequent analysis established that variations in load holding time and loading rate exerted by the PBHTA exhibit minimal influence on the Brinell hardness results pertaining to steel structural components. Through statistical evaluation, correlations linking Brinell hardness with yield strength and ultimate tensile strength were scrutinized in situ. Validation processes confirmed the precision of Brinell hardness measurements under laboratory scrutiny and in field settings, thus facilitating reliable assessments of yield and tensile strength attributes. The investigation substantiated the feasibility and dependability of deploying PBHTA directly for on-the-spot Brinell hardness assessments of structural steel, affirming its effectiveness in ensuring safety and reliability standards are met. The use of PBHTA for in situ testing of steel mechanical properties has the advantages of high accuracy and good repeatability. [ABSTRACT FROM AUTHOR] |
