Double angles L 102 x 76 X 9.5 Long legs back-to-back Problem 3 Two L102 · 76 · 9.5 structural steel angles (see below for cross-sectional properties) are used as a compression member that is 4.5 m long. The angles are separated at intervals by spacer blocks and connected by bolts (as shown), which ensure that the double-angle shape acts as a unified structural member. Assume pinned connections at each end of the column, and use E= 200 GPa for the steel. Determine the Euler buckling load for the double- angle column if the spacer block thickness is (a) 5 mm (b) 20 mm. xH STX 76 mm 76 mm ΓαΖ Spacer thickness Mass per meter Area A Designation tan a 106 103 103 106 mmº mm mm mm mm mm mm mm kg/ m 20.2 12.6 8.60 L102 x 76 x 15.9 x 76 x 9.5 x 76 x 6.4 mm 2510 1600 109 0 1 2.50 1.64 1.14 37.4 23.6 16.2 31.2 32.0 32. 3 34.8 32.3 3 1.0 mm 2 2.0 13. 9 9.59 1.19 0.787 0.554 21.5 22. 2 22.5 22.0 19.7 18.4 16.0 16.2 16.2 0.534 0.551 0.558 1
