“…Structures can sometimes be subjected to extreme events (impacts, hurricanes, terrorist attacks, earthquakes, etc) or exposed to a range of degradation actions such us corrosion or fatigue [1,2,3,4,5]. These events can cause the sudden loss of local elements and trigger a cascading failure, known as "progressive collapse" [5,6]. Since a progressive collapse of buildings or bridges can have dramatic consequences, this topic has recently attracted significant attention in the field of structural engineering [7].…”

“…Most studies on progressive collapse focus on buildings [7,[10][11][12][13] or bridges [5,[14][15][16][17] with dramatic consequences due to the large number of lives lost. In the case of buildings, most research is carried out by theoretical studies or experimental lab tests.…”

“…Works on bridge robustness and progressive collapse are basically approached by numerical or analytical studies and, to a much lesser extent, by experimental tests. To date, only two scientific publications are known to exist [5,18] in which experimental lab studies were carried out on full scale steel truss bridges; these structures were subjected to various types of damage and their capacity to open up alternative load paths (ALPs) was investigated.…”

“…These approaches can demonstrate (or not) that the structure has a minimum level of robustness and highlight potential areas for improvement, extracting conclusions to increase the resilience of a structure against accidental actions. Research studies to date have concentrated on both computational simulations (e.g., [3][4][5][6][7][8][9][10][11][12][13][14][15][16]) and experimental analysis (e.g., [17][18][19][20][21][22][23][24][25][26][27][28]), together with studies of real events of progressive collapse [29][30][31][32].…”

Building progressive collapse is currently one of the hottest topics in the structural engineering field. Most of the research carried out to date on this topic has been focused on the structural analysis of the failure of one or more columns in a building to determine the Alternative Load Paths (ALPs) the structure can activate. Past research was mainly focused on extreme situations with high loads and large structural deformations and, to a lesser extent, research looked at lower loads used in design accidental situations, which requires a different set of assumptions in the analysis. This paper describes a study aimed at analysing accidental design situations in corner-column removal scenarios in reinforced concrete (RC) building structures and evaluating the available real ALPs in order to establish practical recommendations for design situations that could be taken into account in future design codes. A wide parametric computational analysis was carried out with advanced Finite Element (FE) models which the authors validated by full-scale tests on a purpose-built building structure. The findings allowed us to: (i) establish design recommendations, (ii) demonstrate the importance of Vierendeel action and (iii) recommend Dynamic Amplification Factors (DAFs) for design situations.

Bridge collapses are catastrophic events with countless consequences. However, bridge engineering has progressed thanks to the knowledge acquired analyzing collapsed structures. In this direction, modern forensic techniques allow detecting weaknesses and vulnerable zones in the structural systems. It has been demonstrated that the data related to bridge failures has been fundamental for engineers to propose and update theories, concepts, and designs in bridge engineering. This paper presents a methodology to analyze the initial damage and its propagation on steel truss bridges. The first part of the paper presents a comprehensive review of state‐of‐the‐art and scientific challenges. The methodology is described in detail in the second part of the paper; it comprises two main tasks that are further divided into several activities. This methodology was developed as part of the “Pont3” project and has proven to be of great value in gaining a better understanding of how progressive collapse occurs in steel truss bridges. By using this methodology, it is possible to detect initial damage and evaluate the structural behavior of steel truss bridges, which will ultimately lead to safer and more reliable structures.
