Abstract
Stress-strain state of I-beams was determined using experimental data. Method of preliminary stress inducing to I-beams by a local thermal effect allowing increase in load-carrying capacity of compressed I-beam columns and improvement in structure of steel in the HAZ zones forming in fabrication of welded I-beams was suggested.
Keywords: I-beam, local thermal effects, residual stresses
