Mechanical properties of CFT column and steel beam joint with inner stiffening ring was analyzed by using FEA program ANSYS. Simultaneity, using correlative theory of circular beam, stress distributing rule of stiffening ring was induced. The multi-dimensions joint is different from the annular plane in bidirectional. Not only the turn of beam-annular stress concentration, but also lied on the oblique angle, smaller of the angle easier to form the biggest stress area. Thickness of stiffening ring can impact on load absorption of enforced plane. Results of FEA are valuable methods for design of stiffening ring.

Abstract This paper presents the numerical modelling of strengthening a steel-concrete composite beam. The main assumption is that the strengthening is not the effect of the state of a failure of a structure, but it resulted from the need to increase the load-bearing capacity and stiffness of the structure (for example: due to a change in the use of the object). The expected solution is strengthening without the necessity to completely unload the structures (to reduce the scope of works, the cost of modernization and to shorten the time). The problem is presented on the example of a composite beam which was strengthened through welding a steel plate to the lower flange of the steel beam. The paper describes how energy parameters are used to evaluate the efficiency of structures’ strengthening and proposes an appropriate solution.
