“…In two previous studies [20], [21], the authors analysed the wind load effects on the 516 Arouca Bridge and presented a design approach to analyse the quasi-static and dynamic behaviour of the bridge through theoretical, analytical, and numerical models. The uncertainties, when it comes to defining the structural and loading parameters in the serviceability assessment of footbridges, led to an in situ experimental work that validated the assumptions made during the design phase [22], [23].…”

“…The amplitude of natural frequency is influenced by the number of pedestrians. To develop a numerical model and perform dynamic analysis, natural frequencies and vibration modes must be known [21]. In general, walking frequencies for pedestrian bridges are within the range of 1.6 to 2.4 Hz [22,23].…”

Temperature is the main driver of bridge response. It is continuously applied and may have complex distributions across the bridge. Daily temperature loads force bridges to undergo deformations that are larger than or equal to peak-to-peak traffic loads. Bridge thermal response must therefore be accounted for when performing load rating and condition assessment. This study assesses the importance of characterizing bridge thermal response and separating it from traffic-induced response. Numerical replicas (i.e., fine element models) of a steel girder bridge are generated to validate the proposed methodology. Firstly, a variety of temperature distribution scenarios, such as those resulting from extreme weather conditions due to climate change, are modelled. Then, nominal traffic load scenarios are simulated, and bridge response is characterized. Finally, damage is modelled as a reduction in material stiffness due to corrosion. Bridge response to applied traffic load is different before and after the introduction of damage; however, it can only be correctly quantified when the bridge thermal response is accurately accounted for. The study emphasizes the importance of accounting for distributed temperature loads and characterizing bridge thermal response, which are important factors to consider both in bridge design and condition assessment.

Structural deterioration is a complex problem that can compromise the safety and functionality of buildings, bridges, walkways and other structures. The damage found is diverse, including corrosion, as well as cracks and fissures at specific points. Throughout this article, the challenges faced in dealing with this problem have been discussed, highlighting the different techniques and technologies used for assessment, diagnosis and repair. The objective of this work was to carry out a case study on the revitalization of the footbridge on BR-010 in the city of Imperatriz. The research was carried out with a qualitative and quantitative nature of a descriptive nature, using the technical procedure of exploratory and bibliographical research. Thus, the present study addresses a work to revitalize a reinforced concrete walkway and studies on this topic to provide more basis for research. A technical analysis was carried out on site and it was found that the structure had many fissures, cracks and corrosion that compromised its functioning. These failures could cause the progressive deterioration of the walkway, making it more fragile and prone to accidents. Due to this fact, the structure's corrective maintenance process was used, so that it could return to its original state and not compromise the integrity of users.
