I am running into some problems with punching at corner columns. My software designs for the maximum shear stress at a point due to biaxial bending. ACI 421.1 suggests that this may be overly conservative due to stress redistribution. They recommend designing for vu at a distance 0.4d from the...
I'm using the 318-05 (I'll refer to the 08 from here on out). I ask because I know several engineers who take d as 0.8h per 11.4.3 (318-08). It does say "Where provisions of 11.4 (section on strength of members with shear reinforcement) are applied to prestressed members..." How this is...
Section 11.5.3. of ACI 318 specifies the valiable "d" in prestressed members to be a minimum 0.8*h. In punching checks, if you elect NOT to design per 11.12.2.2 (which includes of the tendon component in the shear capacity), and instead use the typical 4rt(f'c)bd, would it be appropriate to...
