The member is designed as axially loaded with the followiral a louds: live loud, 130 kips; dead load, 200 kips. Use f = 4000 psi and f, = 60 000 psi. Without actually selecting bars, assume about 2 % total reinforcement e divided in the opposite faces of the member. Use ACI moment magnifier melo (400 mm square section; 5.5 m clear height; LL = 580 kN; DL = S90 EN . 30 MPa: f, = 400 MPa). 15.2 Determine the adequacy, including length effects, for a 14-in.-diameter spirally reinforced column (assume about 2% reinforcement) which is an interior second floor column (Column A) in the bruced frame of the figure for Problems 15,2 15.8. The member is to carry an axial service load of 87 kips dead load and 13a kips live load, with only the dead load considered sustained. The 14 x 22 beams contain p=0.015 for negative moment tension steel. Use f =5000 psi and f, = 60,000 psi. Use the ACI moment magnifier method. (350 mm diameter.
