subject: Geotechnical Engineeringbook: principle of foundation engineering - Braja M Das

It is proposed to build an 8-story building with a footprint of 20 m x 30 m, resting on a mat foundation of the same dimensions, in a saturated clay with undrained shear strength of 60 kPa. Assume approximately 12.5 kPa per floor for dead and live loads. Unit weight of soil is 18kN/m3 . a) At what depth would you place the mat to make this a fully compensated foundation?b) What would be the depth of this mat foundation for the net factor of safety of 5?c) What is the gross factor of safety for the depth determined in the answer to question b)?

A proposed office building will include a 10 ft x10 ft square, 3 ft deep (the footing height is also 3 feet) spread footing. The normally consolidated clay has the following engineering properties: Ydry = 115.0 pcf $'=24° c'=90.0 psf Cc/(1+eo) = 0.15 The soil stratum extends to a great depth, and the ground water table is 50 ft below the ground surface. Using the classical piece-wise log-linear method, estimate the total settlement of this footing considering only the allowable bearing pressures using ASD approach. The unit weight of concrete is 150 pcf. State any assumptions made.
