# Development Length Calculator

Development Length. The concept of "de-velopment length" of reinforcing bars was intro-duced in the 318-71 ACI building code [1971]. provisions in the Code attempt to account for the many variables affecting the tension develop-ment length, d, of a straight bar. These variables include: Bar size Yield strength of the bar
