Single Fastener in Tension and Shear Near an Edge Based on ACI 318-02
INPUT DATA & DESIGN SUMMARY
CONCRETE STRENGTH
fc' =
SPECIFIED STRENGTH OF FASTENER fut = ksi
     (The strength of most fastenings is likely to be controlled by the embedment strength rather
     than the steel strength, so it is usually economical to use ASTM A307 Grade A fastener.)
FACTORED DESIGN TENSION LOAD Nu = k

CHECK CONCRETE BREAKOUT STRENGTH :
= k Nu

       y3 term is 1.0 for location where concrete cracking is likely to occur.
CHECK PULLOUT STRENGTH :
= k Nu
where : f =
       y4 term is 1.0 for location where concrete cracking is likely to occur.
CHECK SIDE-FACE BLOWOUT STRENGTH : (Since c > 0.4hef , this type of failure mode is applicable.)        
= k Nu
where : f =
DETERMINE DESIGN TENSILE STRENGTH :
= K
CHECK FASTENER SHEAR STRENGTH :
= k Vu
where : f =
= k Vu
where : f =
       y7 term is 1.0 for location where concrete cracking is likely to occur.
       AV/AVo and y6 terms are 1.0 for single shear fastener not influenced by more than one free edge.
       l term is load bearing length of the anchor for shear, not to exceed 8d.
= k Nu
where : f = 0.75
       y3 term is 1.0 for location where concrete cracking is likely to occur.
kcp = for hef > 2.5 in.
DETERMINE DESIGN TENSILE STRENGTH :
= K
CHECK TENSION AND SHEAR INTERACTION :
Since Nu 0.2 f Nn and
Vu 0.2 f Vn
