In the petrochemical business, it is quite common to see structural steel braces built from WT shapes. If you like Table 4-12 in the AISC 15th Edition, then you might like the attached example plots which I built on the same principle. AISC 15th Edition LRFD maximum axial capacities in kips; KL in feet Maximum […]
