UOSD Foundations Engineering & Reinforced Concrete Design problem
Description
A square foundation (B×B) has to be constructed in layers of sand and clay (for bearing capacity calculations assume c’=0).
Given:
- Water table is at 15 ft below ground surface.
- Unit weight above and below water table=124 pcf
- Phi’= 32 degrees
- Foundation Embedment depth (Df)=4 ft
- Soil Average Elastic Modulus (Es)=250 ksf
- Allowable settlement=1.0 in
- (non factored) Vertical Load, Q = 133 kips
- Two-way shear Load, V = 29 kips
- Two way bending moment, M = 200 kips – ft
- FS=3.0
Determine:
-Bearing capacity curves for general shearfailure and settlement (show curves graph)
-Determine footing size under the givenloads
-Check against sliding
-Structural design of the footing (includesthickness of the footing and steel rebars and their spacing)
