Checking the low track lattice girder bridges for robustness

Abstract When you say about a thing or a being that they are robust, you imagine a complete entity from the point of view of its component parts giving out force and safety. The notion of robustness is associated with a lot of activity domains. Consequently, there are many definitions individualizing the robustness notion depending on the study domain. The work aims to join in the present day studies with a new research in the bridge domain. The object of the study is represented by three low track steel lattice girder railway bridges. In the article there is also presented the way the structural robustness notion is to be found in the national codes.
