    Shear Friction Reinforcement VS. Max Steel Area

    So if I have a bending moment around a corner of a wall that req's As = 0.31 sq.in. of steel, and the shear values exceed the allowable Vc and I need to use Shear Friction, do I not have to "add" additional steel? If Avf = Vu/(phi*Fy*mu) = 0.09, do I not have to use 0.40 sq.in of reinforcing?

    Shear Friction Reinforcement VS. Max Steel Area

    Does reinforcing area used for Shear Friction according to ACI 318 section 11.7 count towards the maximum steel percentage for 0.75pb?

    Autocad 2004- Cannot select viewport line

    I'm using version 2004. I've got two viewports in paperspace, and in the last 20 minutes I've become unable to select the viewport to move, stretch, erase, or anything. Any thoughts?
