Notes:
Values given shall be used directly for members with normalweight concrete
and Grade 60 reinforcement. For other conditions, the values shall be modified
as follows:
a) For lightweight concrete having equilibrium density, w in the range of 90
to 115 lbt, the values shall be multiplied by (1.65-0.005we) but not less
than 1.09.
b) For other than 60,000 psi, the values shall be multiplied by (0.4+ f/100,000)
