Abstract:In the U.S., the specified yield strength of primary reinforcement of special concrete moment frames and special concrete shear walls may not exceed 60 ksi. As part of the Applied Technology Council ATC-98 Project, the use of high-strength reinforcement as primary reinforcement for seismicforce-resisting systems (SFRS) was studied. The purpose of the project was to examine the feasibility of using reinforcement with a specified yield strength greater than 60 ksi and, if feasible, to recommend changes in design requirements and reinforcing steel specifications. The use of ASTM A706 Grade 80 was specifically examined, and it was determined that Grade 80 reinforcement could be used with little change to ACI 318. It was also found that additional research is needed before complete recommendations for use of Grades 100 and 120 reinforcement can be made.
