Load Acting on a Pile Group

The pile group can be used to found both bridge abutments and arbitrary civil engineering structures. To determine the load acting on a pile group can be rather complicated. The load can be applied at several locations as concentrated load (column), distributed along the line (wall), or over the area. The procedure shows a simple way of determining the load at a given point by adopting an arbitrary static program.

  1. We start from the model of a structure in the static program
  2. Providing no joint is defined in the center of the pile cap, we introduce it.
  3. A fixed support in all 6 directions is assigned to the joint (fixed, fixed, fixed, fixed, fixed, fixed)
  4. If the joint is not found on the pile cap (beam model), we connect it with the actual structure (The stiffness should correspond to other elements)
  5. Apart from the new joint, we remove all boundary conditions on the analyzed model
  6. Perform analysis - the joint reactions correspond to the load, which is input into the "Pile group" program - the function for importing the load can also be utilized

Note: internal hinges found in the structure must be changed to fixed-end supports for the static program to find a solution.
