Skrebtsov S. Stability of the compressed steel double-T elements after regulation of a residual stress conditions on the part of length

The subjects of dissertation researches are sanctified to theoretical generalization and experimental ground of methods of determination of the residual stresses state (RSS) in the rental and weld-fabricated elements of double-T profile after his adjusting to pieces of length and to the account of influence of RSS at the calculations of the compressed elements of constructions. The method of determination of firmness of the compressed elements of the double-T crossing is improved after adjusting of RSS on part of length. The experimental methods of researches are improved and data are first got about the change of RSS, which arises up in the compressed elements of the double-T crossing after hits adjusting on part of length. The degree of influence of RSS is experimentally set on firmness of the compressed elements. The results of numeral researches are first got and set rational application of the worked out analytical vehicle domain. Keywords: steel columns, residual stresses state, adjusting on part of length, firmness, strength.
