“…During the 2014 floods in Serbia, 307 bridges were damaged, and the total losses for transport infrastructure were estimated to be €166.5 m, with a reconstruction cost of €128 m [1,16]. In literature, extensive research is done related to scour actions to the bridges including numerical studies [17][18][19][20] and monitoring studies [21][22][23].…”

The extreme river streamflow that occurred during floods in 2010 in Montenegro caused significant damage to infrastructure and road facilities. The most severe damages were located on bridges crossing the river Lim, where a rapid water level increase in several municipalities led to failure or damage of almost 20 bridges. In this paper, a damage assessment of four significantly damaged reinforced concrete (RC) bridges, located in the affected zone of 40 km, is conducted. One bridge in Berane (bridge 1) and three bridges located on roads upstream from Berane (bridges 2, 3, and 4) were analyzed. Extreme water levels and inadequate flow profiles caused great damage to the bridges of which the piers were not adequately founded. A scouring process under the foundation of piers and abutments located in the riverbed occurred due to surface erosion and degradation of alluvial sediments. Applied methods and techniques for reconstruction and structural strengthening of bridges are presented in detail as well as results of conducted analyses of the design reconstruction process. In order to design appropriate structural strengthening, nonlinear analyses of bridges due to the settlement of the piers were performed. The research findings can be used in the vulnerability assessment and reconstruction planning phases for other bridges in the considered zone.

This article discusses developing a methodology based on visual inspection for quantifying bridge damage (WABIM). The proposed methodology was developed through the application of weighted averages and a case study. Many current visual inspection methodologies, manuals, or guides related to bridges only allow qualitative results to be determined. Consequently, a high degree of inefficiency and inaccuracy was identified in the results from traditional methodologies; since they have a subjective approach, the results merely depend on the observer. Therefore, a methodological proposal was generated that allowed qualitative results to be described quantitatively, increasing the objectivity of the analysis and the accuracy of bridge maintenance plans. Rating ranges are used with weighted averages for each pathology, applied directly to the structural elements of the bridges. The classification guidelines and pathologies of bridge structures are adapted according to the Manual for the Visual Inspection of Bridges and Pontoons of Invías, Colombia. The case study was developed on a bridge in the city of Pereira, Colombia, presenting more significant surface deterioration and equipment deterioration. The WABIM methodology identified that periodic maintenance is required and the intervention's emphasis.
