RECONSTRUCTION OF THE CITY RAILWAY AND THE RESULTS OF ITS NATURAL TESTS

Abstract

Constructive solutions for the reconstruction of the overpass bridge through the railway tracks on Horodotska Street in Lviv are presented in this article. The bridge deck is expanded from the dimension G - 10,5 + 2 * 0,9m to the dimension G -16,5 + 2 * 1,5m in the combined way - symmetrical completion of two extreme beams with unilateral cantilevered overhangs 2,7 m and the device between these beams monolithic reinforced concrete billboard. Beams are reinforced by changing the static scheme from split to frame-inseparable

Tests of the overpass bridge after reconstruction confirmed the effectiveness of the design decisions and the possibility of working of the overpass on the normalized temporary loads A15 and NK100, for which the reconstruction was designed.
