“…It was deduced that the circular pattern improves the connection strength and enhances the energy dissipation capability of the system compared to the rectangular pattern (Figure 5). This phenomenon is the result of the circular connection's improved distribution of bolt forces [13].…”

Bolted joints are widely used in the aerospace and automotive industries due to their ease of assembly, disassembly and design flexibility. Optimizing threaded fasteners is essential to achieve uniform load distribution and minimize the number of bolts required, thereby reducing system cost and weight. This review paper aims at summarizing the five optimization techniques available in the literature, including bolt layout, tightening strategies, tightening sequences, bolt size, and stresses. The purpose is to emphasize the importance of optimizing bolted joints via the proper selection of materials, geometry, patterns, and bolt sizes, to obtain efficient joints with low assembly time while maintaining strength.

“…In [2], static and cyclic experiments were performed on a circular bolt configuration, including additional numerical studies. It was shown that such a circular configuration could have a more even load distribution than rectangular bolt configurations and that the energy dissipation was increased.…”

Designing bolted endplate connections is a typical problem in practice. Nevertheless, the calculation of such endplates is not that easy. Due to the deformation of the plate, the resultant prying forces influence the resistance of the connection. The so‐called T‐stub model considers prying effects and is included in the EN 1993‐1‐8 for typical endplates with two bolts and rectangular bolt configurations. It was found in the literature that circular bolt configurations can have some benefits compared to rectangular ones, like a better stress distribution in the plate and bolts, resulting in higher resistances. Systematic research on the evolution of the yield‐line mechanisms is still not available, which is the focus of the presented study. We investigated and compared the yield‐line mechanisms and ultimate loads of typical rectangular and circular bolt configurations. A parameter study has been worked out by varying the endplate thickness for each case. The calculations were made with the Discontinuity Layout Optimization (DLO) concept, directly offering the kinematic mechanisms and corresponding ultimate loads. Finally, we gave some simple recommendations for calculating the ultimate loads of circular bolt configurations.

The aim of this paper is the development of the two different numerical techniques for the preloading of bolts by the finite element method using the software Abaqus Standard. Furthermore, this paper gave detailed guidelines for modelling contact, method for solving the numerical error problems such as numerical singularity error and negative eigenvalues due to rigid body motion or the problem of the extensive elongation of bolts after pretension which is occurring during the analysis. The behaviour of bolted joints depending on the two different approaches of pretension was shown on the example of an extended end-plate bolted beam-to-column connection under the monotonic loading. The behaviour of beam-to-column connection was shown in the form and moment-rotation (M-ϕ) curves and validated by experimental test. Advantages and disadvantages of pretension techniques, as well as the speed of numerical models, were also presented in this paper.
