ON THE QUESTION OF ARCHITECTURAL IMAGE OF THE HOLY TRINITY TEMPLE IN PRZEMYSL

The article deals with the issue of the lost heritage of the Eastern Christian culture of the city of Przemyśl. Being in the area of intense Latin religious expansion, the city underwent numerous transformations and changes, which led to the loss of almost the entire authentic layer relating to the most ancient and Rus` periods in its history.

PROSPECTS OF RECONSTRUCTING THE ATTIC OF THE MAIN BUILDING OF THE LVIV POLYTECHNIC UNIVERSITY FOR EDUCATIONAL AND OFFICE PURPOSES

H. O. Hnat (20001)The article deals with the issues of adapting premises in the attic of the main building of the Lviv Polytechnic National University for educational and office purposes, in order to increase the number of lecture rooms in the Institute of Architecture and to improve educational process.

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.

TO THE QUESTIONNAIRE OF THE OPERATING CONDITION OF SPAN CONSTRUCTIONS OF ROAD BRIDGES IN WESTERN AREAS OF UKRAINE

By using the examples of large – scale inspections of iron – concrete 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.

THE RESULTS OF EXPERIMENTAL RESEARCHS OF THE REINFORCED CONCRETE BEAM SPAN STRUCTURE OF THE BRIDGE BY RECONSTRUCTION STAGES

On the network of state and local roads, a significant number of bridges with precast or monolithic span structures of small and medium spans are constructed according to TP-56. At present time, their normalized period of exploitation of 25–30 years is exceeded in 2–2.5 times and they continue to be exploited with unsatisfactory exploitative and technical and economic parameters. Therefore, for further normal exploitation, they need to be reconstructed with the restoration of normalized exploitative parameters.

OPERATIONAL STATE, RECONSTRUCTION AND TEST RESULTS OF RECONSTRUCTED HIGHWAY OVERPASS

The small and medium span bridges constructed in the 50-60s of the last century with span structures of prefabricated reinforced concrete beams according to the typical project of 1956 year currently do not meet modern exploitative requirements and require reconstruction with bringing of their technical characteristics in accordance to the requirements of the current design norms for new bridges.

Dynamic Monitoring Of The Historic Centre Buildings For A Solar Elements Arrangement

The possibilities of integrating the solar power elements into formed environment of historic cities are considered in the article. Using the example of a historic city area of Chernivtsi it has been realized a multi-level dynamic monitoring of the buildings and presented the results of preliminary calculations of an energy efficiency of a roof photoelectric elements installation.
