Abstract
In this laboratory experiment three sub-experiments were carried out. The first test consisted of a simple Euler strut. The test was conducted to understand the behaviour of a simple structure with a rectangular cross-section. The test was completed succesfully although some mistakes occured between theoretical and empirical results. The second experiment consited of an unsymmetrical beam, of which the determination of its principal axes was made. Then the third experiment, shear centre, was conducted in order to find the shear centre. Finally, all the experiments were completed, and the objectives were met, even with the presence of errors, which were mostly due to machinery and apparatus inaccurasy.

1. Introduction
All structures are subjected to loading from various sources. The main categories are: dead, imposed and wind loads. The most widely used material for different types of structures in civil engineering is metal. A metal consists of aluminum
