welded overlapped longitudinal reinforcing bars, which have cross-sections varying in length and are interconnected by electric arc welding. The strength of reinforcing bars of a composite cross-section was compared with the strength of individual centrally stretched reinforcing bars. As a result of the experiment, the influence of the main factors on the strength of the bars was investigated: electric arc welding; stress concentration; eccentricity of the application of longitudinal tensile force, as well as the distribution of forces in the sections of each element along the length of the composite reinforcing bar-sample.
