4. 2L100x100x8 are welded together to form a box section
as shown. It is used as a compression member to support a
vertical load, P. The column is hinged on its top and fixed
at the bottom (k = 0.70). Determine the largest allowable P
that the column can carry if it has an unsupported length of
4m. Use A36 steel (Fy = 248 MPa)
Properties of an L100x100x8:
Area = 1551 mm²
Moment of Inertia, Ix = ly 1448 x 10³ mm4
