The main aim of this project was to carry out experiments involving deflection of thin-walled structural members and further analyze them in detail to enhance the comprehension of these members. This was motivated by the fact that thin walled members finds their way in most engineering applications of modern day society. This project aided in gaining a comprehensive and better understanding of thin walled structures and their behavior during deflection. This was done based on two theories namely; Castigliano's theorem and Shear Center analysis. The document has engaged a clear step by step procedure on the analysis of these two propositions and this could further be used in improvements of modern mechanical designs.

An illustration of what has been done by other Institutions in effort to demonstrate these two propositions has been noted and in this project and in this project, we aim to demonstrate them experimentally by carrying out laboratory tests using fabricated specimens designed to exam these two theories.
