Shearwall Reinforcements
Shearwall reinforcement design results and inadequacy of shears are displayed in the Shearwall Reinforcement dialog. In the shearwall reinforcement dialog, shearwall transverse and longitudinal reinforcements, head zone reinforcements, internal forces calculated as a result of the analysis, increased internal forces related to TBDY, and capacity ratio results are given. The body and head area reinforcements of the shearwalls can be changed and fixed in the Shearwall Reinforcement dialog.
