Effect of mesh on load pattern
The finite element mesh regularity and intensity has an effect on the load pattern process. The following example best explains the process.
Load pattern for four-panel slab
Actual pattern areas for an irregular coarse mesh
Actual pattern areas for an irregular fine mesh
With the finer mesh, the point load will not be included and there will be less additional area load in the pattern loading.
Actual pattern areas for a regular coarse mesh
Drawing design strips significantly improves the mesh. See Chapter 18, "Generating the Mesh" for more information on improving the mesh.
