Consider the cross-section shown below. Assume the cross-section is subjected to an external axial
force of 300 kN applied at the origin of the reference system shown (the origin is located at mid-height
of the section). Note that the flanges have different thicknesses.
Assume linear-elastic material properties and the section to be made of steel with elastic modulus
E = 200 GPa.

(i) Provide two qualitative floor layouts for the primary and secondary beams for the Floor Layout A
(Floor Layout A is shown above). Make sure to clearly draw the 2 floor layouts highlighting primary
and secondary beams. Comment on the advantages and disadvantages of the two floor layouts with
respect to one another.
(ii) Consider Floor Layout B (Floor Layout B is shown above) and sketch one qualitative floor layout in
which you provide qualitative locations of the columns, primary beams and secondary beams.
Comment on the benefits of your selection of the positions of the beams and columns.

Consider the two composite columns shown below and denoted as columns 1 and 2. These columns
have same gross area but differ in the geometries of the steel and concrete components. In particular,
the square steel hollow section in section A-A (for column 1) has thickness of t, while the square steel
hollow section in section B-B (for column 2) has thickness of 2t.
