5-20. A welded built-up 16 in. x 16 in. box column in the bottom story of a highrise building ismade up of 3 in. thick steel plates (A992 Grade 50). Assuming the column has an unbracedlength of 14 ft., determine the following:a. The gross area, A,, of the column.b. The moments of inertia about the x-x and y-y axes, I and I,, respectively,c. The radii of gyration about the x-x and y-y axes, r, and r,, respectively.d. Using the LRFD method, determine the axial compression strength in kips for thecolumn.e. Using the column load tables, select a wide flange or I-shaped column of A992 Grade50 steel that has the same axial compression load capacity as the box column and com-pare the weights of both sections. Which of the column section (built-up box section orI-shape) is more economical?

As per Bartleby's guidelines we are supposed to answer only first three questions. Kindly repost…
