2. Verify that a built-up ASTM A572 Grade 50 (Fy - 345 MPa) column with PL 205 x 25 mm flanges and PL 380 * 6 mn web is sufficient to carry a dead load of 300 kN and live load of 900 KN in axial compression. The column, having an unbraced length of 8 meters, is braced at the midpoint about the weak axts, the ends are pinned in both axes. (Use ASD, 15 pts)

4. Use A992 steel and select the lightest W12-shape for the beam-column shown in the figure below. The member is part of a braced frame, and the axial load and bending moment are based on service loads consisting of 30% dead load and 70% live load (the end shears are not shown) Bending is about the strong axis, and K= Ky=1.0. The frame analysis was performed consistent with...
A W14 × 74 of A992 steel, 16 feet long, is used as a column in an unbraced frame.
A W14 × 74 of A992 steel, 16 feet long, is used as a column in an unbraced frame. The axial load and end moments obtained from a first-order analysis of the gravity loads (dead load and live load) are shown in Figure P6.7-2a. The frame is symmetric, and the gravity loads are symmetrically placed. Figure P6.7-2b shows the wind load effects obtained from a first-order analysis. All loads and moments are based on service loads, and all bend-ing moments...

Problem 5: Design of Idealized Compression Member A 20-ft long column is pinned at the bottom and fixed against rotation, but free to translate, at the top. It must support a service dead load of 110 kips and a service live load of 110 kips. a) Select the lightest W12 of A992 steel. Use the column load tables b) Select the lightest W18 of A992 steel. Use the trial-and-error process.
