SITUATION 1 Verify the adequacy of column AB, part of a sway frame structure, to carry the loads shown in the figure. The column is made of ASTM A992 steel (Fy 50 ksi). Use LRFD specifications. For determining its effective length factor, neglect inelastic effect. W18x50 L= 35 ft k= 800 in." L= 35 ft C I= 800 in." Webs of columns and girders are in the plane of the frame. W24x55 W24x55 L= 35 ft k= 1,350 in." L= 35 ft =1,350 in. A Po = 100 kips P = 300 kips Po = 41.5 kips P = 125 kips > W14x82 L= 14 ft ly = 881 in. W14x82 L = 14 ft x = 881 in.
