Design upthrust (favourable): Ud = YG fav x Ukb = 4.9 kPa© Design bearing pressure (effective stress): q'^d = qEd - ud = 176.6kPa

Material properties and resistance

From previous calculation, characteristic material properties are: undrained strength cuk = 45 kPa, shearing resistance ^ = 25 cohesion c'k = 5 kPa

Partial material factors for SLS: Ycu = 1 , Y^ = 1 and Yc = 1 © Design undrained strength cud = cuk + Ycu = 45 kPa

Design shearing resistance p>d = tan 1 (tan(p>k) ^ Yp) = 25° Design cohesion c'd = c'k + Yc = 5kPa
