$2-$ Design a suitable foundation to carry two columns $C_1,C_2$ spaced at $6\mathrm{.}0m$ and

shown in Fig. $(1)$ for the following data: $C_1$:$40x40cm,LL=500kN$&$DL=$

$700kN,$ lies near a property line. $C_2$:$6060cm,LL=900kN$&$DL=1200$

$kN.$ The safe bearing pressure of soil is $150k\frac{N}{m^2}$ and the characteristic material

strengths are $f_c=24$MPa and $f_y=420$MPa. The level of the top of footings is

$1\mathrm{.}0m$ below the ground surface. Draw a neat sketch showing reinforcement

details.
