- Design a square tied column to support an axial dead load D of 130 kips and an axial live load L of 180 kips. Initially assume that 2% longitudinal steel is desired, fc' = 4000 psi, and fy = 60,000 psi.

The floor system shown below supports a uniform dead load of 100 lb/ft² and a uniform live load of 40 lb/ft?. Draw the loads with magnitudes on the following structural members: а) BI b) В2 с) ВЗ d) B4 e) Gl f) G2 g) G4 6 @ 7' = 42' C4 G1 B3 B2 2 @ 15' = 30' G4 G3 G2 BT 5 @ 6' = 30' 42' 36' For the same floor plan shown above and assuming the same floor loads and that the building consists of four floors, determine the following: a) The dead load on column Cl in the first floor. b) The live load on column C2 in the second floor. Consider live load reduction. c) The sum of the dead plus live loads on column C3 in the third floor. Consider live load reduction. OT
