High-Strength Concrete and Reinforcing Steel in Beam-Column Connections
Based on test results made of normal-strength reinforced concrete, Joint ACI-ASCE Committee 352 has developed design recommendations for joints of special moment frames including requirements of moment strength ratio, shear strength, confinement, and development length. Due to the interests of the reinforced concrete industry in using high-strength reinforcement for special moment frames, ACI-ASCE Committee 352 appointed a task group to review available test data in the past 30 years and constructed an unified database of 357 beam-column joints made with normal-strength and high-strength concrete. Based on the database investigation and experimental verification, we concluded that current ACI 318 design provisions can be extended to include the use of high-strength reinforcement with modifications in the requirements of joint effective area, confinement, and development lengths. Provided information can be referred for further updating the design recommendations of beam-column joints for high-strength reinforcement.
