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.

Bolted joints, which are one of the detachable joining methods, are used extensively. The reliability of bolted joints is extremely important for the strength and life of the system. The determination of the number of bolts to be used in a system, the position and other data of the bolt requires very serious design and engineering studies. In this study, the design and optimization of bolted joints subjected to lateral forces are performed. For this purpose, a software has been developed in C# programming language. The software visually guides the user and asks a minimum number of questions to the designer and all other parameters are calculated by the program. The visual design of the program was done in Visual Studio environment. The graphic designs used in the software help the user to enter correct data. When the program is run for bolted joint under lateral loading, the user only enters the number of plates and force as input. Although the program performs its calculations between 1.5-2 factor of safety, it is possible to change it according to the characteristics of the design. The program developed in the light of these inputs calculates the appropriate bolt diameter, number, material and dimensions of the plates for the designed joint according to the optimum design options. The design options determined by the program are also presented to the designer visually. With the developed software, the user workload is minimized by determining the optimum options of bolted joints according to the minimum amount of user input. This resulted in significant savings in the time spent in design and engineering calculations. The user-friendly interface provides an easy and visual use. The results obtained by the program were also solved manually to check the reliability of the program.

Considering bolted parts, Rakotondrainibe et al (2022) potentially optimized the shape and topology of each part as well as the position and number of the bolts. Li and Young (2021) conducted an experimental study on open section members under an eccentric load used in steel structures.…”

In this study, a software has been developed for calculating static strength of bolted steel plates. This software has been developed by adding equations covering the bending moment that occurs during a tensile test as well as under real loading conditions. In order to test the accuracy of this program, 5 samples with the M6 bolt connection were prepared. In addition, the simulation result was compared with the experimental work performed with tensile tests and the finite element analysis made in Ansys.
