ASTM A 36 steel with
Fy = 36 ksi
Fy = specified minimum yield stress of the type of steel being used
minimum yield point (P&A 268)
(MSC 2-4 & 5-202)
Maximum allowable bending stress = 0.66 Fy
may be used when:
-----------------------
1. symmetric beam section
2. web and flanges with min. width-thickness ratios
3. braced compression flange
