A proposed building plan is Figure $1.$ Structural analy sis yielded the column loads. The building will be placed on the soil profile, with the soil properties presented.

Consider a mat foldadation and determine the allowable bearing capacity using minimum mat size $($DAS$/$CH$6).$ Check settlement criterion as well, ensuring the differential settlement beneath the mat does not cause angular distortion.

Check if the minimum mat size is safe in carring the given loads.

Do complete structural design. $f_c^{\text{'}}=21$Mpa,$f_y=400$Mpa columns:

$5050cm.,E_S=15000k\frac{N}{m^2}$

You may make reasonable assumptions, if necessary.
