Design of a Column in Ground FloorLoad on the Column: ( 3.34*14.5/2) + (3.16*15.17/2) + (2.9*13/2) + (2.99*13.67/2) >> 87.47 kip ( For Each floor )

Self weight of the column : 1*2.5*108*150

>> 40.5 kip >> (40.5*1.4) >> 56.7 kip

Total load on the Column: 87.47*10 + 56.7

>> 931.4 kipAccording to ACI Code, For, Tied column: = 0.65

Pu = 0.8[0.85fc(Ag - Ast) + fyAst]

Considering, = 0.03 ; So, Ast = 0.03Ag

>> 931.4 = 0.65*0.8[0.85*3.5(Ag 0.03Ag)] + 60*0.03Ag

>> Ag = 382.25 in2

Considering, Ag = 360 in2 Then the required steel area comes,

931.4 = 0.65*0.8*0.85*3.5*360 - 0.65*0.8*0.85*3.5Ast + 0.65*0.8*60Ast

>> Ast = 12.63 in2
