Vertical Shear Reinforcement in Shear Walls
Vertical Shear Reinforcement in Shear Walls
(OP)
Hi
I am wondering whether we have to add vertical shear reinforcement calculated as per Cl 11.9.9.4, Eq 11-30 ACI 318-08
with the reinforcement calculated for vertical load and in-plane Bending Moment.
In my case, for low shear wall with high shear force, as per Eq 11.30 vertical shear reinforcement requirement is 0.75%
and for vertical load and in-plane moment as per PCA Column output I need 0.35% reinforcement.
In this case, should I provide total vertical reinforcement as 1.05% or maximum of shear and axial load demand i.e. 0.75%
Please suggest
Regards

I request you to elaborate on the concept of providing maximum of [Shear Demand or (Axial + Bending demand)].
Please suggest a suitable reference for this criteria.
Thank you very much for your help

As for the shear reinforcement, you can calculate it easily by assuming that the forces is entirely carried by the links.
