2. Design the steel requirements for a 7 m, 600 mm X 600 mm square tied column, as shown in the Figure below, in an unbraced frame. The effective length factor is 1.0. Use fc = 20.7 MPa, fy = 413.7 MPa and place the bars in the two end faces only with d' = 75 mm. Use NSCP 2001. Use conservative formula for El. Use load combination of 0.75 (1.4DL +1.7LL +1.7WL). Pa-850 KN Pu= 900 KN PNL = 150 KN fr M = 200 kN-m Max = 140 kN-m M₁-180 kN-m MpL = 30 kN-m My = 40 ky-m MWL = 80 kN-m braced frame unbraced from (a) due to gravity load. (6) due to wind Load
