The article represents a summarized research of the influence of thickness of elements connected
by multiple-bolt friction joints produced onto the bearing ability of the connection. Different
thicknesses of structural elements connected by multiple-bolt friction joints produce both qualitative
and quantitative influence on the stress-strain state of the connection.
The relevance of the research is driven by the technology of Light Steel Framing Construction
(LSFC) that is intensively developed and implemented in the construction industry.
The objectives of the research encompass:
the experimental study of the influence of the thickness or thickness difference of connected
elements produced onto the bearing capacity of friction joints;
identification of the bearing capacity of high-strength bolts with controlled tension in the
bolted connection, depending on the thickness of connected elements.
The results of experimental tests of samples of connected plates, the thicknesses of which
vary from 1.5 mm to 5 mm, are presented in the paper.
The analysis of connections that have, at least, one plate the thickness of which is less than
5 mm, should incorporate the coefficients that take account of the bearing capacity fluctuations.
The authors demonstrate that the bearing capacity of friction joints of steel plates is highly
dependent on the thickness and thickness difference of connected plates. Different combinations of
thicknesses of plates within the range of 1…5 mm cause the bearing capacity of the joints to vary
within the range of 130 %.
