Peretyatko I. . Deflected mode of steel beams and columns strengthened by stripes with intermittent welds

In dissertation calculation methods of deflected mode of flange steel beams and columns which were strengthened with stripes welded by intermittent fillet welds were developed. Proposed methods consider full uploading of constructions before their strengthening. Experimental analyses of deflected mode of flanged beams strengthened by intermittent welds were carried out. Experimental results were compared with results obtained by theoretical calculations based on proposed methods. Obtained theoretical solutions were applied in calculation of deflected mode of flange beams and columns strengthened by intermittent fillet welds. Influence on deflected mode of this construc-tion such factors as: strengthening by fillet or intermittent fillet welds, conditions of loading, degree of strengthening welds rigidity were studied.
