Description
Summary:The article considers the results of laboratory tests for different types of bolted joints for the I-beams. The tests were subjected to a steel I-beam cross section with splice joint by friction, flange and combination of the splice joint by friction and flange joints under a bending. A brief review and analysis of existing solutions for bolted joints for girders are given, the main difficulties with the use of welded joints and bolted joints are indicated. The results of laboratory tests of different types of bolted joints for I-beams, using high-strength bolt connections, are presented. The pictures of stress distribution in the elements of joints are investigated, and the deflections of beams using different types of joints are determined. It is shown that the deflections of beams with splice joints are significantly influenced by the ductility of the entire connection. According to the test results, the conclusions about the obtained pliability values are made and the graphs of joint deformation at various stages of loading are given. The obtained pliability values may be used in further virtual experiments.
