Concrete Strength Requirements for Residential Projects in SDC D or Higher

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Fellow Engineers -
Say one was designing a residential project in SDC D or higher with a daylight basement using concrete walls.  The residence above would be wood framed.  ASCE 7-05 says that the concrete walls have to be Special Reinforced Concrete Shear Walls because of the SDC D or higher.  ACI 318-05 Section says that you must use a minimum of f'c = 3,000 psi. Typically one would call out f'c = 2,500 psi for residential concrete so that you don't trigger special inspection, that is until I came across this.  Do either of you know of an exception to this for residential design? Perhaps in the IRC? I don't know the IRC too well.
