Example

A typical floor plan for a $10-$story building is given below. Calculate the load carried by column $C1$ at foundation level using both tributary area and reaction methods.

Assume column weight is $10\%$ of column load.

$t_s=0\mathrm{.}16m,F.C=1\mathrm{.}5k\frac{N}{m^2},L.L=5k\frac{N}{m^2}$

Beams are $0\mathrm{.}25m0\mathrm{.}5m,$ conc. density $=25k\frac{N}{m^3}$

Walls are $0\mathrm{.}25m$ thick and $3m$ height, wall density $=10k\frac{N}{m^3}$
