This paper presents the experimental and numerical analysis of an innovative plate girder geometry with variable web thicknesses. An idea proposed in this research is to increase the stability of the girder web by increasing its thickness in the compressed zone. This solution can replace commonly used longitudinal stiffeners which are designed to prevent web local loss of stability. Moreover, such an innovative approach requires...

W pracy przedstawiono wyniki badań pękania próbek w warunkach asymetrycznego czteropunktowego zginania. Próbki do badań wykonano ze stopu aluminium 2024-T351. Badania doświadczalne obejmowały identyfikację właściwości mechanicznych materiału poprzez przeprowadzenie próby rozciągania i ściskania na próbkach osiowosymetrycznych. Następnie przeprowadzono badania pękania dla płaskich próbek z karbami. Wszystkie próbki do badań miały...

The application of advanced quality control tests for welds is essential for enhancing competitiveness in thewelded construction industry. The global focus on obtaining energy from alternative sources is leading to the increased production of wind towers. Improving the method of conducting inspections is necessary as wind tower structuresare subject to 100% quality control of welded joints. The article presents the comparison of...

Offshore wind power is experiencing rapid development around the world. The number of installations and their size is growing. Thousands of monopile support structures with diameters of 10 m and weights of 2000 tons will be installed in the coming years. Offshore wind power installations, often located close to the shore and shipping routes, pose a new challenge to ship safety. The study analyses the damages from an accidental...

Offshore wind farms are developing well all over the world, providing green energy from renewable sources. The evaluation of possible consequences of a collision involves Finite Element computer simulations. The goal of this paper was to analyse the influence of selected strain-based failure criteria on ship damage resulting from a collision with an offshore wind turbine monopile. The case of a collision between an offshore supply...
