6. Conclusions In this paper, the RLA of the iconic Long Bien Bridge in Hanoi is presented. A FEM was created for six spans of the bridge and movable loads representing the historical railway traffic were applied, resulting in stress histories by applying the Rainflow counting. In accordance with the Miner’s rule and considering the corrosion effect, most stresses (riveted) criterion are considered as safe concerning the fatigue behaviour. This modest study is parallel to studies leaded by a French engineering company that has been commissioned by the French Government to study the renovation of LBB.
