What is the reinforcement coefficients for concrete wall?

Reinforcement coefficients for concrete walls : 

Following are the different coefficients of reinforcement used for or a plain concrete wall & reinforced concrete wall. 

1. For your kind information, transverse steel is not required in plain concrete wall construction. 
2. 0.12% & 0.15% vertical steel is required for a plain concrete wall (Important note: 0.12% for HYSD bar and 0.15% for mild steel bar.) 
3. In case of a reinforced concrete wall, 0.4 % minimum vertical reinforcement is provided 
4. Again transverse steel is not needed for reinforced concrete wall 

Thank you.
