“…Two series of numerical simulations were carried out to study the shear connector with regular rectangular cutoff. The details of model calibration and validation are properly described in Caldas et al [29], and were developed according to Cardoso et al [2] and Santos et al [23]- [25]. The first series corresponds to the numerical models developed by Caldas et al [29] to represent the experimental results of shear connectors with regular rectangular cutoff applied in CFST.…”

In this work, a study was carried out on the steel failure behavior of composite dowel shear connectors with regular rectangular cutoff. The bearing capacity equation related to the steel failure is normally treated in the literature as a function of the thickness, yield strength, geometric repetition and shape coefficient. The connector with regular rectangular cutoff study comprised the deduction of the steel failure equation according to von Mises criterion and the comparison of the results obtained from numerical analysis produced for this work and experimental results from literature. The shape coefficient found in each phase of the study is presented. Furthermore, from the numerical results it was possible to evaluate the stress distribution on the steel dowel and verify the coherence of the mechanical model that considers a straight critical section and a uniformly distributed load due to the concrete pressure on the steel dowel.

Bolts cannot be loaded axially according to real field conditions in assembly lines. The main reasons for this are that the loads cannot be applied centred due to the plate thickness and the holes are wider than the bolt. This creates a change in the shear loads on the plate connections due to the moment. Therefore, in this study, a software including additional equations has been developed to reveal the moment formation which the bolts are exposed to. This program, prepared in Matlab software, first determines whether the material properties and thickness of the plate can withstand this tensile force when two bolt-connected plates are subjected to tensile force. If the plate is resistant to these tensile forces, the calculation is continued and the maximum shear stress on the bolts is calculated. For the experimental study, 5 samples with M6 bolt connections were prepared and tensile tests were carried out. The accuracy was measured by comparing the software result with the tensile tests and the finite element analysis results made in the Ansys program. In addition, a method for topology optimization is presented in order to improve the position of the connections on the plate.
