Problem Description
Gravity concrete columns in structures assigned to SDC D, E, or F may have been designed incorrectly for shear.
ACI GRAVITY COLUMN SHEAR DESIGN UNDER EARTHQUAKE FORCES*: In columns not designated as part of the seismic force resisting system, with SDC D, E or F; and whose factored gravity axial forces were greater than the specified by ACI 318 11, at 21.13.4.3 it didn't meet the referenced requirements of 21.6.5 and 21.6.4. Effect: The shear design of Gravity columns with SDC D, E or F may have been inadequate.
Reason
ACI 318-11 21.13.4.3 requires gravity columns in high seismic areas subject to high axial loads to be designed using the provisions for transverse reinforcement in 21.6.4 and 21.6.5. These provisions were not checked by the program.
Solution
Problem corrected in version 15.04.00.00.
