A Review on design and analysis of steel bridge with identification of load bearing capacity

Strengthening old bridges is an increasingly relevant strategy for risk prevention and operation continuity in management of infrastructures. Transportation networks are subjected to progressively stricter environmental load conditions, leading a growing number deficient structures, also due aging deterioration. However, employable resources finite, from both economic points view. For these reasons, strengthening opportunities should be considered as viable option, improving with low impact. With this perspective, selection some the most interesting techniques truss steel presented. To address effective solutions, frequent problems railway first Literature analysis experts’ interviews were conducted compared results obtained representative bridge cluster. Different solutions addressing highlighted then collected qualitatively evaluated, terms efficacy on structural typical construction requirements. Finally, general remarks recommendations based evidence
