“…The useful and well-known structural applications of aluminium are presented by Mazzolani [1]. Aluminium alloys may also be used in complex multi-layered structures, for example, aluminium-concrete composite beams [2][3][4], aluminium-timber composite beams [5] and blast-or impact-resistant panels [6]. These structures are exposed to static or dynamic loads.…”

The present study focused on the behaviour of the AW-6060 aluminium alloy in peak temper condition T6 under a wide range of loads: tensile loading, projectile and explosion. The alloy is used as a structural component of civil engineering structures exposed to static or dynamic loads. Therefore, it was crucial to determine the material’s behaviour at low and intermediate rates of deformation. Despite the fact that the evaluation of the strain rate sensitivity of the AW-6060 aluminium alloy has already been discussed in literature, the authors of this paper wished to further investigate this topic. They conducted tensile tests and confirmed the thesis that the AW-6060 T6 aluminium alloy has low strain rate sensitivity at room temperature. In addition, the fracture surfaces subjected to different loading (tensile loading, projectile and explosion) were investigated and compared using a scanning electron microscope, because the authors of this paper were trying to develop a new methodology for predicting how samples had been loaded before failure occurred based on scanning electron microscopy (SEM) micrographs. Projectile and explosion tests were performed mainly for the SEM observation of the fracture surfaces. These tests were unconventional and they represent the originality of this research. It was found that the type of loading had an impact on the fracture surface.

“…Furthermore, the calculation procedure for steel-concrete composite elements was used to calculate the load-carrying capacity of the ACC beams. The bending resistance of the ACC beam from the analytical estimations was 1.05 times higher than the bending resistance from the tests (Polus & Szumigała 2019a). What is more, non-linear 3D finite element models of the ACC elements used in the bending test and 3 in the push-out test were developed and verified against the experimental results.…”

“…However, the clear ance made it easier to install demountable shear connectors through the holes in the alumin ium beam flange. The behaviour of the ACC beams with profiled sheeting and of said shear connectors was investigated in the bending tests by Polus & Szumigała (2019a). The tested ACC beams showed signs of rib-shearing failure.…”

involvement in the organisation of the 14th International Conference of Metal Structures is perceived by me as a distinction, but also as a proof of trust in the University. This activity fits perfectly the University mission to educate at all levels of higher education and in lifelong learning programs in close connection with scientific and research development. Nowadays, Poznan University of Technology offers education at 9 fac ulties, covering a total of 33 fields of study. Nearly 16,000 students study here and over 1,300 academic teachers cater to their education. The didactic offer of Poznan University of Tech nology covers the most important fields related to modern technology with a recently launched program in Artificial Intelligence; it is also well adapted to the requirements of both domestic and foreign employers. High-quality scientific research is an integral element of Poznan University of Technology strategy, characterized by scientific achievements of its employees who published more than 2,000 scientific contributions: highly ranked articles, monographs, textbooks and other publications. The total number of PUT Library collections is over 450,000 volumes. Among numerous achievements, the University is proud of the H2020 Marie Sklodowska-Curie Global Fellowships and ERC grants. Furthermore, our sci entists are among the authorities of the Polish Academy of Sciences (9 representatives) and are also members of numerous international scientific societies. According to Shanghai Rank ing 2020 edition in disciplines, PUT was classified among the best 400 universities in the world in Mechanical Engineering. Also, we are ranked by students as the most popular university in Poland according to the Ministry of Science and Higher Education in the 2020/2021 academic year.Owing to EU funding, recent years have introduced the development of research infrastruc ture at the Warta university campus. In 2020 our University also became a leader of European University EUNICEa project funded by the European Commission with a budget of more than 6 million EUR. Our university consortium partners originate from Belgium, Germany, France, Finland, Italy and Spain. EUNICE's main goal is to build a common European Uni versity of the future, and prepare its structure and management design within 3 years. EUNICE is aspiring to provide a high-quality digital learning, offering flexible and multidis ciplinary studies, as well as opportunities for students and staff for international exchange and networking. EUNICE will develop modern and innovative pedagogical methods and provide enhanced student services, in terms of enrolment, recognition, student counselling and guid ance aimed at boosting the employability of all students. Just recently, PUT was also granted by the European Commission a follow-up scientific project REUNICE. This H2020 strategic project for the European University Alliance EUNICE aims at aligning its education, research and innovation strategies through an ambitious and transformative agenda.Therefore, I am ...

“…The aim of design is to use their advantages. Although steel–concrete members are the most commonly used, other such as aluminum–concrete [ 1 ], aluminum–timber [ 2 , 3 ] and timber–concrete elements [ 4 , 5 ] can be applied. The paper analyzes steel–concrete beams typically considering concrete as operating under compression and steel I-beam operating under tension.…”

This paper presents results of numerical analysis and experimental research on strengthening of steel–concrete composite beams. Studied members consisted of IPE200 I-beam and 90 × 700 mm reinforced concrete slab. The steel part of the section was strengthened by welding additional steel plates at the bottom. The study was performed for plate thickness ranging between 6 to 22 mm. Spatial FEM models were developed to account for material and geometric nonlinearities and for stress and post-welding strain. Proposed numerical models were experimentally validated. One aim was to find an optimum solution which would minimize cost and maximize bending capacity. To achieve this, energy parameters available in numerical simulations were reviewed and analyzed. Recoverable strain energy value determined in Abaqus was used to find the optimum solution.
