REGULATION OF STRESS-DEFORMED STATE IN COMPRESSED ELEMENTS OF STEEL FRAMES

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.

THE PROBLEM OF CASTLE RUINS CONSERVATION WITHIN THE RESTORATION ACTIVITIES FORMATION

The article reveals the history of the restoration activity formation on the example of the
castle ruins restoration in Ukraine and Europe during the 19th-20th centuries.

architecture. And in the 19th century, an understanding of the value of such architectural objects
was developed, and various methods for their preservation began to be proposed. Stylistic

Switching 300 MW Power-Generating Units with Gas-and-Oil-Fired Boilers to Increased Load Mode

The goal of the research is to develop the guidelines for increasing the capacity of the operating 300 MW power-generating units by using the allowances assumed at the design computations and manufacture of the power-generating equipment, while preserving its reliability criteria and performance efficiency. The capacity of the operating power-generating units is increased in three stages.

OPERATING STATE OF SPAN CONSTRUCTIONS OF EXISTINGMETALLIC BRIDGES ON AUTOMOTIVE ROADS IN THE WESTERN AREAS OF UKRAINE

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.
