Example 11 (TBEC 2018 section Z-I-2.1.): Reinforced concrete building with 6 floors and 1 basement will be constructed on a soil deposit with shear strength parameters of c, = 250 kPa and ou = 0°. Unit weight of the soil is given as 19 kN/m³. Depth of the foundation is 3.5 m and dimensions of the raft foundation is 14m x 19m. Under the static condition and with 1.4DL+1.6LL load combination, maximum foundation pressure is determined as 364 kPa whereas, in earthquake condition with 1DL+1LL+1E, maximum foundation pressure is given as 216 kPa. Calculate the ultimate bearing capacity by using General Bearing Capacity equations and determine whether the foundation is safe or not.
