Calculation of the load capacity of the pile group Abaqus
This example been chosen from Example 8.6 Sam Helwany book
In this example , we calculate the long-term load capacity of the pipe group
Pile group consisting of four concrete piles and each pile has a square cross section with length and width 0.6 m
The interaction between the pile and the soil is simulated using a penalty-type interface between the pile and the soil with a friction factor of 0.3
This question will be modeled based on drained condition. The drained condition will indicate low loading rate . Also during the analysis , the pore water pressure will be zero
The soil layer is assumed to be elastoplastic, obeying the cap model with cap hardening properties
Also must be defined the initial void ratio and Geostatic stress for saturated soil
Since the Model is symmetric in this question , we will simulate one-fourth of the Model
This question will be done in 3 steps
The step 1 is used for applying the weight of the soil and pile
The step 2 is an intermediary step
In step 3 , a vertical displacement is applied to top surface of the pile
