Bearing Capacity of a Square Foundation Abaqus

Bearing Capacity of a Square Foundation Abaqus

This example been chosen from Example 6.3 Sam Helwany book

In this example , we calculate the bearing capacity of a 3m * 3m foundation

The three-dimensional model analyzed is shown in Figure 6.12. The sand layer is 50 m deep and 100 m * 100 m in plan. The loaded area is 3m * 3m. The model considers only one-fourth of the sand layer and the loaded area

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

In this example we establish the load–displacement relationship for the 3m * 3m footing. The bearing capacity of the footing can be obtained from the load–displacement curve
