구조용 고강도 강재 개발 및 적용 현황

To enhance the structural efficiency in the design and construction of tall buildings, this research aims to develop 800MPa grade high-strength steel and its application. As a preliminary stage of the research, this paper presents the required properties of the high-strength structural steel based on several code specifications, and then summing up the properties of pilot products according to the requirements. Regarding the application, this paper reviews some design strategies and also introduces several instances using the high-strength structural steel.
