Bolt Yield Limit Equations for Single Shear

 

Wood-to-Wood

direction of load to grain

 

dowel bearing strengths

F_e// and F_e⊥

Hankinson formula for other angles  (textbook section 6.8, NDS appendix J)

F_eθ = F_e//F_e⊥ / (F_e// sin²θ + F_e⊥ cos²θ)

 

reference design values

Z_// = load // to grain in both main and side members
Z_s⊥ = load ⊥ to grain in side member and // to grain in main member
Z_m⊥ = load ⊥ to grain in main member and // to grain in side member
Z_⊥ = load ⊥ to grain in both main and side members

tables only for loads ⊥ and // to grain, not for angled loads

Steel Side Plates

1/4-in. ASTM A36 steel

 

dowel bearing strength

NDS appendix I

hot-rolled plates  (t ≥ 1/4 in.)	Fe = 2.4Fu / 1.6 = 1.5Fu
cold-formed plates  (t < 1/4 in.)	Fe = 2.2Fu / 1.6 = 1.375Fu

 

reference design values

Z_// = load // to grain in wood member
Z_⊥ = load ⊥ to grain in wood member

F_e = 7500 psi for f'c ≥ 2500 psi
