En el perfil mostrado en la figura corresponde a una edificio a un edificio con planta de 30 x 22.5m de la cimentación se hará con un sistema de 6 zapatas aisladas cada una sujeta a una carga de 600 ton. y cuatro zapatas corridas perimetrales sujeta a 40 ton/m, todo el sistema se desplantara a 3m de profundidad. El Ym de la arena y la grava del suelo sobre el N.A.F. es de 1.9 ton/m2.Zapata corrida

Descargas:
Ymh= 1.9 (3)= 5.7 Ton/m2
Area de excavación= 30(22.5)= 675 m2
Descarga total del suelo= 5.7 (675)= 3840 ton.
Descarga por columna: 1920/6 columnas= 320 Ton por columna
Descarga por zapata corrida: 1920/105= 18.3 ton/mCarga neta por columna: 600 – 320= 280 Ton
Carga neta de zapatas corridas: 40 - 18.3= 21.7 Ton/m
