Given (4- A sTIere footing is 1.8 x 1.8 m with a 0.4 x 0.4 m2 square column. It is loaded with an erial load of 1800 kN and Mx = 810 kN.m; My= 260 kN.m. Undrained triaxial tests give d-36 and c'=20 kPa. The footing depth D= 1.8 m, the soil unit weight y = 18 kN/m, the water table is at a depth of 4.2 m from the ground surface. What is the ultimate load Qu by using general bearing capacity equation. %3| (0.62 ,0.66 ,0.68(0.72) and 2- (0.20 (0.24),0.28,0.32) -> L
