AB  - In the past few decades, demountable connectors have often been used for
connections in composite and mixed steel-concrete structures to reduce
construction time and costs. Furthermore, the application of demountable
connectors enables the reuse of structural elements in these structures, which leads
to sustainable design and a circular economy. In this paper, the demountable
connector is made out of two parts: (1) mechanical coupler and rebar anchor placed
in formwork before casting the concrete element, and (2) steel bolt used for
connecting steel to the RC element. Although this connector is increasingly being
used in contemporary building structures, its behaviour in composite connections is
still insufficiently defined. The paper presents the results of experimental tests and
numerical analysis of the connector with a mechanical coupler, focusing on the local
behaviour of the tapered threaded connection between the mechanical coupler and
rebar anchor.

AB  - 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 [2] and [1]. 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 and 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.

AB  - Problems involving contact are of great importance in industry related to mechanical and civil
engineering, but also in biomechanics and other applications. The contact interaction between
surfaces and different bodies like in a bolted splice connection joint or area in which a tire interacts with the soil is not known a priori, leading to a nonlinear boundary value problem. Due to the rapid improvement of modern computer technology, one can today apply the tools of computational
mechanics to analyze contact problems with required accuracy, depending on design requirements. However, even now most of the standard finite element software is not fully capable of solving contact problems, including friction, with robust algorithms. The aim of this paper is to present some basic concepts of Contact Mechanich.
