Abstract: The test rig consists of a steel framed structure designed to support the engine and actuator. Tubular steel components are gaining popularity in because greater strength-to-weight, greater design properties such as moment of inertia, section modulus and radius of gyration and high resistance to torsional loading, excellent properties of the circular hollow section as a structural element in resisting compression, tension, bending and torsion. Circular hollow section has proved to be the best shape for elements subjected to wind, water or wave loading. The circular hollow section combines these characteristics with an architecturally attractive shape. Structures made of hollow sections have a smaller surface area than comparable structures of open sections. This in combination with the absence of sharp corners, results in better corrosion protection. Typical KT joint in the test rig column is analyzed by using Finite Element Methods by ANSYS software. The design of the typical joint was done according to European Standard EN 1993-1-8, 2005.
