# Vierendeel truss

## 1. Introduction

A Vierendeel truss is a lightweight deep beam or girder structural concept. The goal of this exercise is to determine the deformation and stress state of the aluminium Vierendeel truss shown below, in particular the maximum stress around the lightening holes.

## 2. Model/Geometry

First, we need to build the model, which we are going to do using the Gmsh-software.

The overall dimensions of the model are: 200x125x5 mm.

Dimensions in the Gmsh-model are in meters.

The finished geometry and the meshed model with 2 mm mesh-size:
