Figure 5a shows a 6 m high steel column with the cross-section shown in Figure 5b. The column is used in a lab test to carry a steel block of weight W = 250 kN suspended from a stee arm cantilevering from the top of the column as shown in the figure. The column is fixed at its base and braced at the top and at 3.0 m from top in the x-direction and free to move at the top in the y-direction as shown in Figure 5a. Determine if the column will yield or buckle under the weight of the suspended block. Given: E = 200 GPa, ơy = 250 MPa, A = 8,920 mm?, Ix = 60 (10) mm*, ly = 19 (10°) mm.

Transcribed Image Text:Figure 5a shows a 6 m high steel column with the cross-section shown in Figure 5b. The
column is used in a lab test to carry a steel block of weight W = 250 kN suspended from a steel
arm cantilevering from the top of the column as shown in the figure. The column is fixed at its
base and braced at the top and at 3.0 m from top in the x-direction and free to move at the
top in the y-direction as shown in Figure 5a. Determine if the column will yield or buckle under
the weight of the suspended block.
Given: E = 200 GPa, ơy = 250 MPa, A = 8,920 mm?, Ix = 60 (106) mm, ly = 19 (10) mm.
