ACI318-99: Cl.No. 10.15

[Murali27]

Dear All,
ACI Cl.No: 10.15 — Transmission of column loads through floor system.

Is this clause also applicable to concrete shearwalls?

Thanks in advance

I would say that the code here does not explicitly include shearwalls. But a shearwall is sort of like a very long column and I perceive that the principle is the same - a fear that a very high strength column/wall supporting a floor structure with less f'c might have a weak link in the chain of limit states that is an abrupt failure (punching shear).

Now with walls, there is usually not a huge amount of shear but the concept is that you make your weakest link a ductile failure rather than a brittle failure.

Codes are minimum requirements - nothing prohibits you from using 10.15 for walls.
