“…This knowledge, in support of the information provided by monitoring systems, is essential for interpreting the current state of the structure and for deciding whether it is necessary to implement interventions aimed at avoiding major accidents. Among the different computational strategies, the recently proposed Applied Element Method (AEM) [13][14][15] satisfies the need to simulate both continuum and discrete stages of a structure that progressively reaches collapse, tracking the behaviour from the elastic stage to cracking, crushing, yielding of reinforcements, element separation and collision [16][17][18][19].…”

This paper presents the application of a Structural Health Monitoring (SHM) strategy for bridges affected by slow deformation phenomena to a curved roadway bridge undergoing slow landslide‐induced movements. The chosen multidisciplinary approach is based on the combination of remote sensing data through satellite Synthetic Aperture Radar Interferometry (InSAR) and structural analysis up to collapse investigated through the Applied Element Method (AEM). The results of the application to the considered case study demonstrate that the integration of the displacement information obtained through InSAR technique with the numerical analysis allows for improving the comprehension of the health state of the bridge undergoing slow movements and identifying potentially critical conditions for the structure.

“…Recent studies have demonstrated as AEM is capable of predicting with a high degree of accuracy the structural behavior from the elastic stage to crack initiation and propagation, steel yielding, up to element separation and collision. This modelling approach has been effectively employed to perform collapse simulations of different types of structures, bridges included [8][9][10][11].…”

This work aims to explore the potential of the Applied Element Method (AEM) for structural analysis application in the framework of bridge monitoring, focusing in particular on the aspects of model calibration and simulation of the collapse behaviour. An AEM model of a curved roadway bridge undergoing slow landslide-induced movements was built and calibrated by using the results of ambient vibration testing and modal identification. A simulation under increasing displacements caused by the landslide was carried out, predicting the deformation evolution of the bridge and comparing it with the current state of damage observed on site.

Prestressed concrete frames with infill walls (IW‐PC frames) are commonly used in civil engineering as a structural element. The possibility of structures undergoing progressive collapse is a cause for concern due to its severe consequences. This has become a significant topic in the academic community in recent years. However, research on the resistance of IW‐PC frame structures to progressive collapse is still insufficient. Therefore, this paper investigated the dynamic effects of progressive collapse on the IW‐PC frame, reinforced concrete frame with infill walls (IW‐RC), prestressed concrete frame (PC), and common reinforced concrete frame (RC). The study was conducted using the finite element software OpenSees. The study revealed that the vertical displacement during stabilization of the IW‐PC frame increased by 92.5% and 71.7% compared to the IW‐RC frame and decreased by 93.9% and 92.6% compared to the PC frame for middle column and side column failure, respectively. Additionally, the IW‐PC frame exhibited the highest dynamic load carrying capacity, which was 7.67 and 7.56 times higher than that of the RC frame, respectively. The mechanical properties of the frame were altered by the coupling effect of prestressed tendons and infill walls, making the IW‐PC frame more monolithic.
