Can the formulas from Table J3.5 LRFD Vol. 1 be used for ASTM A153, Grade B5 (Fu=100ksi, FY=80ksi) and Grade B7 (Fu=125ksi, Fy=105ksi) ?
In other words can you use the Tension Stress Limit equations:
Thds. incl. in shear plane: 0.98Fu-1.9fv <= 0.75Fu
Thds. Excl. from shear plane: 0.98Fu-1.5fv...
Would this be correct?
DL M = 8(24) = 192k for nor. wt. conc.
Mu = 10(120) = 1200 k' (assume seismic load)
Mu ot = 1200 - 192 = 1008k'

For a Reinforced normal weight concrete Shear Wall say 12' thick, 16' long, 10' high. The wall has a lateral force at top of wall of 120k. The Wall is to connected to the foundation with dowels. What is the accepted way to design the connection (The dowels) for combined uplift and shear friction...
