The article is devoted to the regulation of the stress-strain state in the compressed elements of steel frames under full operating load. It is proposed to perform reinforcement of such elements with different end eccentricities of load application by rational regulation of the stress-strain state in the reinforcement elements. It is shown that the use of SDS adjustment for frame racks increases their bearing capacity and reduces deformability and welds. The new proposed technology of SDS regulation and possible constructive decisions are offered.

By using the examples of large – scale inspections of metallic bridges the defects and damaqes of elements, the degradation of structural materials are shown. The examples of structure imperfection, tipical defects, operation drawbacks are illustrated. Construction defects are the most numerous and can significantly affect the operational reliability and durability of the surveyed bridges. Basically it is: departure from the project, use of substandard materials and violation of production technology; their share accounts for 55% of the surveyed bridges.
