This paper presents a review of composite structures in which aluminium alloys are used. Current trends in the research of composite structures with aluminium girders and their possible applications in structural engineering were shown. In the presented solutions, advantageous properties of aluminium alloys were exploited, such as high strength-to-weight ratio, corrosion resistance and recyclability. The authors demonstrated the structural behaviour of aluminium-concrete and aluminium-timber composite beams based on their own tests as well as investigations presented in the literature. Furthermore, aluminium-concrete composite columns, a composite mullion made of an aluminium alloy and timber, and a military bridge consisting of aluminium truss components, a stay-in-place-form, reinforcement and concrete were presented. In addition to the description of the structural elements, the main conclusions from their experimental, theoretical and numerical analyses were also demonstrated in this paper. The connection of aluminium girders with concrete or timber slabs provided for the increase of the load-bearing capacity and stiffness, and it eliminated the problem of local buckling in girder flanges and lateral-torsional buckling of girders in the analysed solutions.

W pracy przedstawiono przegląd zespolonych konstrukcji, w których zastosowano stopy aluminium. Omówiono aktualne kierunki badań nad konstrukcjami zespolonymi z dźwigarami ze stopu aluminium oraz możliwe ich zastosowania w budownictwie. W prezentowanych rozwiązaniach wykorzystano zalety stopów aluminium m.in. korzystny stosunek wytrzymałości do ciężaru, odporność na korozję oraz przydatność do recyklingu. Autorzy opisali zachowanie belek zespolonych aluminiowo-betonowych oraz drewniano-betonowych, biorąc pod uwagę własne badania, jak i te znane z literatury. Dodatkowo, scharakteryzowano słupy zespolone aluminiowo-betonowe, słupek zespolony aluminiowo-drewniany zastosowany w konstrukcji fasadowej oraz wojskowy most składający się z kratownicy ze stopu aluminium, szalunku traconego, zbrojenia oraz betonu. Oprócz opisu elementów konstrukcyjnych, przedstawiono główne wnioski z ich analizy eksperymentalnej, teoretycznej oraz numerycznej. Połączenie dźwigarów ze stopu aluminium z płytami wykonanymi z betonu lub drewna zapewniło wzrost nośności oraz sztywności dźwigarów oraz wyeliminowano problem lokalnego wyboczenia pasa dźwigara oraz jego zwichrzenia.
