WebFor reinforcement concrete design, ACI-318-14 (2014)have 3 limitations: value of yield strength, tensile and yield strength ratio, and elongation of steel reinforcing bars which used in reinforcement concrete. One of three limitation based on ACI-318-14 (2014), tensile and yield strength ratio, limited should not less than 1.25. The WebA s,min = max (0.1·N Ed /f yd ; 0.002·A c) (9.12N) where: f yd is the design yield strength of the reinforcement. N Ed is the design axial compression force. (3) The area of …
