This study describes the structural properties of high-strength 600 Mpa steel developed for high-rise structure. In this study, we introduce the developmental criteria of 600Mpa steel, which was already well-established for its practical use in Japan. Furthermore, this study analyze the mechanical characteristic, axial load test, and flexural test of the same rank of Korean steel by comparing the experimental results from beam-column steel from Japan, providing the fundamental database for the related research field in Korea.
The 600Mpa steel produced in Korea, when compared with that of Japan, exerts high yielding ratio, whereas low elongation ratio. Given this analysis, the yielding ratio should be adjusted below 80%, whereas elongation ratio should be up-regulated more than 20% to utilize for the construction of high-rise structure.
