This article presents an analytical and numerical assessment of load-bearing capacity of a beam-to-column joint. Two possibilities have been examined: a joint reinforced with a fastened haunch on the side of a compressed flange of a beam and a joint with no reinforcement. The load-bearing capacity and rotational stiffness of joint and has been calculated. Distribution of stresses and deformations in particular components of the joint has been determined. The results of analytical and numerical calculations have been compared, proving that the load-bearing capacity of the joint calculated on the basis of analytical approach provides safer results (for a reinforced and non-reinforced joint), and however in certain cases it may lead to oversizing of the connection.
