A built-up compression member with pinned ends in a braced frame consisting of two MC8x20 of A36 steel (Fy = 36 ksi) with a ¾" separation as shown. The total length of the member is 10 ft. and channels are connected through their back-to-back webs with a welded stitch at the midlength. Compute the design axial compressive strength of the column (Øc Pn). Given: MC8x20; Ag= 5.87 in.2 , r x-x = 3.04 in., r y-y = 1.49 in. Note: you need to use Table 4-14 (AISC) (Ans. Øc Pn = 268.85 Kips) Answer is given. Please show me the process of solving this problem and use neat handwriting. Thank you.

A built-up compression member with pinned ends in a braced frame consisting of two
MC8x20 of A36 steel (Fy = 36 ksi) with a ¾" separation as shown. The total length of the
member is 10 ft. and channels are connected through their back-to-back webs with
a welded stitch at the midlength. Compute the design axial compressive strength of the
column (Øc Pn).
Given: MC8x20; Ag= 5.87 in.2
, r x-x = 3.04 in., r y-y = 1.49 in.
Note: you need to use Table 4-14 (AISC)
(Ans. Øc Pn = 268.85 Kips)
Answer is given. Please show me the process of solving this problem and use neat handwriting. Thank you.
