“…Michèle et al (2005) presented that the concentrated loads by vehicles have great influence on lots of welded structures. For now, lots of early fatigue cracks of welded structures have been reported in similar bridges (Backer et al 2008, Aygül et al 2012, Kolstein 2007, Miki and Tateishi 1997, Xiao et al 2008. In order to minimize the restraint caused by the floor-beam web to rib rotation at the support due to unsymmetrical loads, one often designs a cutout hole to avoid the high stress at the bottom portion of the rib.…”

The cutout hole locating at the place of rib-to-diaphragm welded connection is adopted to minimize the restraint, which is caused by the floor-beam web to rib rotation at the support due to the unsymmetrical loads in orthotropic deck. In practice, an inevitable problem is that there is a large number of welding joint's cracks formed at the edge of cutout hole. In this study, a comparative experiment is carried out with two types of cutout hole, the circular arc transition and the vertical transition. The fatigue life estimation of specimens is investigated with the application of the structural hot spot stress approach by finite element analyses. The results are compared with the ones of the fatigue tests which are carried out on these full-scale specimens. Factors affecting the stress range are also studied.

“…demonstrated an analytical method with slope-deflection formulas for bridge deck analysis. Internal moments in the trapezoidal stiffeners forming the orthotropic bridge deck are determined by this analytical approach (Backer et al, 2008). In another study, slope deflection formulations are derived for the tapered beam-columns to determine the critical buckling loads (Riahi and Etezady, 2012).…”

The XXXth International Conference Research for Furniture Industry was held with the cooperation of Poznan University of Life Sciences-Faculty of Wood Technology, Department of Furniture Design and Gazi University-Technology Faculty, Wood Products Industrial Engineering Department on 22–23 September 2022, in Poznań, Poland. Up to the XXVIth annual conferences were held in Poland. The XXVIIth Conference was organized at Gazi University in Ankara with the participation of valuable scientists from 12 different countries in 2015. The XXVIIIth Conference was organized in Poland. The XXIXth International Conference Research for Furniture Industry was organized in 2019 in Ankara and focused on rapid changes in design, production, and marketing strategies in the Furniture Industry. This event will unite all industrial sectors parallel to the developing and changing world. The conference aimed to enable academics, industry representatives, and students to share their experiences/knowledge in the field of engineering, machinery, manufacturing, management, material science, restoration, and protection and upholstery to meet the increasing consumer demands by diversifying; user-oriented, efficient use of natural resources, environmentally friendly approach, CAD/CAM/CAE, construction, design management, eco-design, ergonomics and anthropometrics, furniture industry, furniture mechanics and so on. The exchange of information and ideas should lead to the formulation of new directions for research activities in such areas and therefore support the furniture industry. An essential aspect of the Conference is to teach and acquaint young scientists (students and Ph.D. students) with the theoretical, experimental, and simulation methods used to explore these systems.

The Slope Deflection Method is one of the displacement-based methods developed for structural analysis. In this study, an approach is proposed for the static analysis of continuous beams. The basis of this approach includes the Ricatti Transform, which was used in the literature to get the Transfer Matrix Method by using the Finite Element Method. In this study, Ricatti Transform was applied to the Slope Deflection Method for continuous beams. In the study, firstly, the application of Ricatti Transform to the Slope Deflection Method was shown theoretically, and then two numerical examples were solved to show the application and suitability of the presented approach. With the presented method, the number of system unknowns that are the basis for the solution is reduced, thus saving the analysis time.
