The steel thin-walled structures are widespread in civil and industrial engineering nowadays. Self-drilling screws or rivets are used to interconnect thin-walled elements. Blind rivets and nuts as connectors are considered in the frames of this paper. Rivets have some benefits over self-drilling screws. They are: we can obtain more dense connection when using rivets. So we can increase bearing capacity of connection; a lower cost of riveted connection; a large variety of installation tools for riveted connection: manual, pneumatic, battery; side; an easy installation: access to the connected element is required only from one. These benefits provide increasingly growling popularity to rivets. In the paper 4 types of rivets are considered: combined (aluminum/steel) blind rivets, zinc-coated steel blind rivets, stainless steel blind rivets and blind nuts. The features of each type of rivets are described in the paper. The influence on the behaviour of connections is revealed. The results of experimental research performed by the authors are presented in the paper. A bearing capacity shear of riveted connections is studied in the experiment. There are 3 types of riveted connections subjected to experiment: connection made by blind combined rivets; connection made by zinc-coated steel blind rivets; connection made by blind nuts. A connection between elements with significantly different thicknesses is modeled in the experiment. In reality this situation takes place, for example, in the roofing of buildings, where trapezoidal sheet can be fastened to purlin by rivets. As a result of the experiment the authors found out that the local deformations occuring under rivet head in the thick element significantly affect the behaviour and bearing capacity of the connection. That’s why the results of connection's bearing capacity obtained in tests were lower than the bearing capacity of rivet declared by manufacturers.

A light steel thin-walled structure is very effective. The durability and strength of structures,
investment efficiency, high construction intensity, excellent technical and operational characteristics,
backed by extensive architectural solutions make the employment of the technology of light
steel thin-walled structures particularly efficient in low-rise commercial construction. Light steel thinwalled
structures represent a relatively new area, therefore, the regulatory base required for a reliable
analysis of these st ructures is unavailable, and this fact limits their use in construction. Russia
has no special norms regulating the above parameters. The underdeveloped regulatory framework
in Russia gives rise to the problem of market saturation with cheap low-quality fasteners.
The purpose of testing is to determine the mechanical properties of steel . The tests were applied
to five separate self-tapping screw connections. The purpose of testing was also to determine
the bearing capacity and the stress-strain state of connections.
Numerical calculations using the finite element method required a steel diagram. MGSU specialists
mad e tensile test specimen to determine the physical and mechanical properties of coldformed
thin-walled steel profiles at the "Sector for Testing of Building Structures". Identification of
pliability of connections was required to employ the dependence obtained using numerical calculations
of structures. As a result of the work performed at MGSU, a diagram of thin-walled cold-formed
steel profiles was generated.
