The aim of this paper is to discuss numerical analysis and verification of experimentally tested bolted and weld splice connections in the commercial Abaqus software. The first step in verifying a numerical model with an experimental one is to compare the modal frequencies. The problems that arise when modeling multiple bodies in a contact interaction, such as in the case of bolted splice connection joint, arise from the behavior of the contact itself  and . In order for the numerical model to be stable and without calculations convergence issue, it is necessary to: define an adequate type and size of finite elements, determine the master and slave surfaces, and properly define the constraints and connections of the separate parts of the bolted welded connection structure. Tests with a modal hammer were performed in order to find the oscillation tones of the cantilever beam under consideration, which would be compared with the numerical model. Based on a comparison of numerical a...nd experimental results, it is discussed whether the experimental beam is adequately designed and constructed and the effects of the support and splice connections on the frequencies are considered.
