Example The axial loads for a building column nonspiral rein

Example The axial loads for a building column (non-spiral reinforced) have been estimated with the following results: · D = 150 kips . live load from roof, L 60 kips live loads from floors, L = 300 kips compression wind, Wt- 70 kips tensile wind, W 60 kips service level id td \' seismic compression load, Ec 50 kips . seismic tensile load, Et = 40 kips Determine the required and nominal design loads

Solution

Load combination=1.2 D +1.6 L² + 0.5 Lr + 1.5 Wt + 1E

= 1.2 (150) + 1.6 (300^2)+0.5×60 + 1.5 (70+60) + 1×(40+50)

=180 + 144000 + 30 + 195 + 90

= 144495 kips
