DYNAMIC STABILITY OF THE BRIDGE "GOCE DELČEV" IN SKOPJE
Abstract
This paper presents the dynamic analysis of prestressed reinforced concrete road bridge "Goce Delchev" over the river Vardar in Skopje from the aspect of dynamic stability. The bridge span is 88,00m with overhangs2x29,20m, founded on wells (caissons) whereby the height of the upper edge of the well to the upper edge of the bridge is 14,37m. The longitudinal slope of the bridge is in the gentle slope of 0.57%. Experimental testing on theforced vibrations of the bridge was performed, and then a mathematical model was formed and dynamic analysiswas made. This was necessary, because the superstructure of the bridge is complex cross-section and behaves differently in the longitudinal and transverse direction and the effect of different soil-structure interaction. From all of the above it can be seen that the obtained corresponding influences mutually greatly match.
