Selected construction and technological problems of middle span length steel bridges based on examples over the Danube and Dnieper river

Abstract

Every example of bridge both the aesthetic appearance and technological solutions are unique. Differences are a result of a various historical events, neighbour impact and evolving capabilities of bridge building. Based on the unique features of bridge examples taken into consideration one reveals evolution technology of bridge building in time. The aim is to present some examples of steel bridges which have been considered successful. Bridges are still in use. Each of them was created in different period of time. It shows the altered bridge building idea, fluctuation of trend. The successful design was able to have been improved during time when increasing road traffic forced engineers to adapt bridges into new conditions. Bridge builders found a positive solution to every appeared problem. It help to preserve bridges from being rebuild and clearly showed that bridge building is the finest domain of civil engineering.
