16. 6-19. Determine the LRFD design strength and the ASD allowable strength of the section shown if snug-tight bolts 3 ft on center are used to connect the A36angles. The

two angles, 4x3x3/8, are oriented with the long legs back-to-back(2L4×3×3/8 LLBB) and separated by 3/8 in. The effective length, (Lc)x=(Lc)y=12 ft.
