Abstract
Prior to 2000, majority of reinforced concrete structures were designed using steel reinforcements with yield strength of 400 MPa. The improvement in technology has enabled the strength of reinforcement bars to be progressively higher and a few developed nations have explored and embraced such changes in their construction industries. There are many potential benefits to the use of high-strength reinforcement in elements, these include cost savings, reduced construction time, and reduction in reinforcement congestion. This paper reviews existing research conducted at NTU, Singapore to determine whether there is sufficient information to justify the use of reinforcement with specified yield strengths of 600 MPa or more for special moment frames and to identify performance and design issues associated with the use of reinforcement with higher yield strengths.
