Sažetak
Due to many comparative advantages of aluminium alloys, prefabricated aluminium halls represent one of the most common examples of their application in the field of Structural Engineering. They are mainly designed and built as temporary structures, but today, when economic and environmental resources are very important ; there is an evident need for their permanent usage and consequently their reliable design. For large spans, a typical structural system is made of aluminium frame with steel tension tie element. Aluminium joints of prefabricated halls are almost exclusively formed using bolts in combination with steel reinforcements (e.g. steel inserts embedded into the aluminium column and beam elements). In these joints, the transmission of forces is realized partially through bolts and partially through a complex contact mechanism between aluminium and steel insert. Since simple expressions for behaviour assessment of such joints do not exist, laboratory tests must be necessarily performed. Having that goal in mind, three different types of knee joints were tested under the application of static loading. The first type of specimens consisted of nominal steel joints with a tie element. The second type consisted of two analogical joints with beams made of specially shaped aluminium profiles that were plugged onto steel inserts. The last type consisted of single specimen, exactly the same as the second type, but only without the tie element. Structural properties of all three joint types (rotational stiffness, moment resistance and rotation capacity) as well as the recorded failure modes have been obtained and discussed.
