Bearing Capacity Failure of a Strip Foundation Abaqus
This example been chosen from Example 6.2 Sam Helwany book
In this example , we calculate the bearing capacity of a 0.6-m-wide strip foundation on a thick homogeneous layer of Ottawa sand
The foundation is situated at a depth = 0.38 m, as shown in Figure
The layer of sand is 4.5 m deep and 15 m wide
The concrete foundation is assumed to be linear elastic with a Young’s modulus of 1435 MPa and a Poisson ratio of 0.2
In this analysis , we use two steps
In first step , gravity loads and surcharge loads are applied to the sand layer
In second step , the foundation load is applied using a constant downward displacement boundary condition at the top surface of the foundation
The constant-velocity boundary condition applied to the top surface of the foundation causes the foundation to settle at a constant rate
Theoretically, the foundation pressure can be increased gradually up to the failure point (termed the bearing capacity) at which a failure surface
