ABSTRACT
The structural robustness is a subject often dealt with by the structural designing
engineers and by the researchers, mainly during the last decades. The robustness as a characteristic of the structural systems became an important topic to be studied
following some structural failures. The article aims to present the way a structure of a bridge made out of steel lattice girders, low track, answers to various scenarios for losing some structural elements. They proposed 20 scenarios for the initial damages aiming to find out the key element of the structure and to see if there is or not an alternative way to redistribute the efforts.

Keywords: robustness, bridge, key element, redistributes the efforts
