- Synopsis
- At present the reinforcing bars which require the yield strength of less than 490 N/mm2 are standardized by JIS G 3112 "Steel Bars for Concrete Reinforcement". For steel bars whose yield strength exceeds the above mentioned value, new standard proposals have been made by the National Product Study as New RC. This report discusses the problems of JIS and New RC Drafts and also the differences between those and the proposed standards made by the author. The report introduces the standards for mechanical properties required for higher strength reinforced bars by showing earthquake damages, structural experiments and analyses. The report also contains the mechanical property data of high strength reinforcing bars manufactured with the proposal standard for high rise reinforcing bars.
