Design strength for Tension Members
1 Determine the ultimate loads acting on the structure.
The values of D,L,W,E.etc which they are unfactored service loads (Our mistake in the
midterm lol) and their equations are in the manual on page 28 (LRFD)

Compression Member design
Consider a long slender compression member. If an axial load P is applied and increased
slowly, it will ultimately reach a value P cr that will cause buckling of the column. P cr = , the
values for k differ depend on the supports
