  1. Chapter 6 • Design of Axially Loaded Compression Members • Selection of: • Single shapes • Process (use of AISCM column’s tables): • Table 4-1, page 4-12 to 4-204 AISCM 14th Ed. • Table 4-1, pages 417-607 (4-10 to 4-200) • KL • Try a section • Check section

  2. Example 1 Choose a wide flange W14 section to carry an axial load P . The column ‘s length L and end conditions are shown in figure below. Use Fy = 50 ksiand do all necessary checks conforming to AISCS. P = 530 k L = 20 ft.

  3. Example 2 Choose a wide flange W14 section to carry an axial load P . The column ‘s length L and end conditions are shown in figure below. Use Fy = 50 ksiand do all necessary checks conforming to AISCS. P = 850 k L = 15 ft.

  4. HW Problem 4.1 Choose a wide flange W14 section to carry an axial load P . The column ‘s length L and end conditions are shown in figure below. Use Fy = 50 ksiand do all necessary checks conforming to AISCS. P = 420 k L = 25 ft.

  5. HW Problem 4.2 Choose a wide flange W14 section to carry an axial load P . The column ‘s length L and end conditions are shown in figure below. Use Fy = 50 ksiand do all necessary checks conforming to AISCS. P = 1500 k L = 14 ft.

  6. HW Problem 4.3 Choose a wide flange W14 section to carry an axial load P . The column‘s length L and end conditions are shown in figure below. Use Fy = 50ksi steel and do all necessary checks conforming to AISCS. P = 850 k L = 10 ft.

  7. HW Problem 4.4 Choose a wide flange W14 section to carry an axial load P . The column‘s length L and end conditions are shown in figure below. Use Fy = 50ksi steel and do all necessary checks conforming to AISCS. P = 2100 k L = 13 ft.
