The 2011 edition simplified the calculation of tension development lengths. The formula was refined to: $ l_d = \frac340 \fracf_y\lambda \sqrtf'_c \psi_t \psi_e \psi_s d_b $ In the , $f_y$ and $f'_c$ are in MPa, and $d_b$ is in mm, resulting in $l_d$ in mm. ): Common values like 3000 psi are converted to approx

Historically, ACI has published "M" versions of their codes (e.g., ACI 318M-11). These are not mere translations; they are re-calibrated documents. In engineering, one cannot simply convert pounds per square inch (psi) to megapascals (MPa) and expect the math to work seamlessly with standard material sizes.

ACI 318-11 placed a heavy emphasis on seismic design, refining the requirements for special moment frames and structural walls. The code clarified the detailing requirements for intermediate and special moment frames, ensuring that structures in high-seismic zones possess the necessary ductility to withstand earthquakes.
