Did you know that structural steel is a very efficient material for building bridges? A steel bridge <\/strong>is four times lighter than a concrete one. In modern society, steel bridges play an essential role in the infrastructure of a country.<\/p>\n\n\n\n

Steel bridges are classified according to:<\/p>\n\n\n\n

\u2013 the type of traffic supported;<\/p>\n\n\n\n

\u2013 the type of the main structural system;<\/p>\n\n\n\n

– the position of the carriageway in relation to the main structural system.<\/p>\n\n\n\n

The advantages of steel bridges<\/strong><\/p>\n\n\n\n

\u2013 they can support heavy loads on large openings, while requiring relatively small foundations;<\/p>\n\n\n\n

– steel has an advantage for structures where construction speed is vital, because as many elements as possible can be prefabricated and assembled on site;<\/p>\n\n\n\n

– in the urban environment, where the traffic is congested and the working space is limited, steel bridges can be built with minimal disturbances for the community;<\/p>\n\n\n\n

– a greater efficiency is achieved than for concrete structures when resistance to seismic forces and those produced by wind gusts is taken into account;<\/p>\n\n\n\n

– the life span of steel bridges is longer than that of concrete bridges;<\/p>\n\n\n\n

– due to the small construction depth, metal bridges offer a slender appearance, which makes them attractive from an aesthetic point of view, the reduced depth also contributes to the low cost of the piers.<\/p>\n\n\n\n

The engineers who design the bridges must take into account the distance to be covered, as well as the type of traffic for which it is built. A bridge for cars and trains must be more resistant than a simple pedestrian bridge.<\/p>\n\n\n\n

Structural steel \u2013 efficient material<\/h2>\n\n\n\n

The main advantages of structural steel<\/strong> compared to other construction materials are its strength and ductility<\/a>. The rigidity of steel in relation to its weight is much higher than that of concrete.\u00a0 This material was a natural solution for the construction of bridges with large spans. As early as 1890, the Firth of Forth Bridge, the largest steel bridge at that time, was completed.<\/p>\n\n\n\n

Steel <\/a>is indeed suitable for most of the range of openings, but especially for larger openings.<\/p>\n\n\n\n
