The roof beams of a wear house are supported by pipe columns as shown in the figure. Each columns has outer diameter d2 = 100 mm, inner diameter d1= 90 mm and length L = 4m. The columns have fixed support at the base with modulus E = 210 GPa.
1
If the upper end is pinned and the beam prevents horizontal displacement the critical load Pcr = 437 kN
2
If the upper end is pinned and the beam prevents horizontal displacement the critical load Pcr = 875 kN
3
If the upper end is fixed against rotation and the beam prevents horizontal displacement the critical load Pcr = 875 kN
4
If the upper end is fixed against rotation and the beam prevents horizontal displacement the critical load Pcr = 437 kN
