# Local Compression Analysis

* Objective: *Check the local compression analysis of the foundation

* Task: *Verify the correctness of the local compression analysis

**ARBAT initial data:**

Importance factor γ_{n} = 1

**Load arrangement:**

Local load near one edge of an element |
a = 300 mm |

**Lateral reinforcement by flat meshes:**
