“…Masonry is the oldest building and unique technique for historical structures. In order to understand the earthquake behavior of masonry structures, many studies have been conducted in the literature and earthquake behaviors were investigated using the finite element method (FEM) (Kocak, ; Lourenco, ; Ayala and Speranze, ; Apostolopoulos and Sotiropoulos, ; Betti and Vignoli, ; Bayraktar et al ., ; Bağbancı, ; Foraboschi, ; Gonen et al ., ; Parisi and Augenti, ; Parisi et al . 2013).…”

SUMMARYThis paper presents the results of model calibration conducted on a historical mosque called Hafsa Sultan in Manisa, Turkey. The finite element model of the mosque was calibrated by the use of the results obtained from ambient vibration tests of the structure. In order to develop a solid model of the structure, the dimensions of the structure, defects such as cracks and material degradations in the structure, and the materials used in different parts were identified. For the evaluation of the material properties of the structure, nondestructive and destructive testing methods were used. The numerical and experimental modal parameters of the structure were obtained by finite element method (FEM) and Operational Modal Analysis (OMA), respectively. The natural frequencies and corresponding mode shapes were obtained from both FEM and OMA and compared with each other. While a good compatibility was achieved between mode shapes, some differences between natural frequencies occurred. It was thought that the differences resulted from variations in the Young's modulus of masonry, cracks in elements or boundary conditions. Therefore, the finite element model was calibrated by changing material parameters. Finally, a more realistic numerical model of the mosque was put forward and the results were discussed in detail.

“…Many experimental studies have also been carried out to investigate the applicability of these analysis methods. In recent years, it has been aimed to get closer to the actual behavior by transferring the experimental data taken on real bridges to numerical analysis [5][6][7][8][9][10][11][12][13]. In order to determine the stress points of the historic Mus Murat Bridge under certain loads, analysis was performed with a finite element method.…”

This study was carried out to determine the strength of long span stone bridges and stress areas of a historical bridge by using finite element method during earthquakes, floods, and vehicle traffic. The possible earthquake impact of the region and the behavior of the bridge under the effect of the 2011 Van earthquake were investigated. The stresses that will be caused by hydrostatic and vehicle loading applied to the bridge are dwelled on. This study aimed to shed light on future restoration work. As a result of the vehicle, hydrostatic load and dead load analysis, the biggest deformation occurred in the arch K9, which has the largest arch span. According to the results of the earthquake analysis, maximum deformation occurred in the K10 arch, which is one of the arches with the largest arch span of the bridge. In addition, inearthquakes affected in the X and Z direction, it was observed that the arches and piers in the middle of the bridge, that is, these relatively higher structural elements were subjected to more stress. It has been determined that the A11 pier of the bridge is the structural element exposed to the most pressure.

“…The existing bridge management system (BMS) includes several methods [38,40]: (i) the grey system theory and Bayesian networks; (ii) analytic hierarchy process (AHP) and fuzzy comprehensive evaluation (FCE); (iii) comprehensive evaluation based on onsite inspection. The grey system theory and Bayesian networks are used to predict bridge technical conditions [41].…”

Lessons Learnt from Bridge Collapse: A View of Sustainable Management

Bridge failure is one of the worst infrastructural disasters. This paper investigates the risk of bridge infrastructures in the view of sustainable management. Statistics on bridge failures from 2009 to 2019 in China show that most of these failures are related to anthropic factors. The collapse of the Zijin Bridge on 14 June 2019 in Heyuan City of Guangdong Province, China is used as a case to perform detailed analysis. Superficially, bridge collapse is a technical problem rather than a management problem. However, the deep reason for this kind of bridge failure may be due to the lack of sustainable management. In order to verify this point of view, both fault tree analysis (FTA) and strategic environmental assessment (SEA) for the bridge failure and later impact on society are conducted. According to the FTA results, the failure of the arch foot is the direct trigger of the Zijin Bridge collapse. Since a lack of real-time monitoring, risk assessment and other management issues are potential factors causing bridge collapse, strategic environmental assessment (SEA) is used to investigate the management issues related to the economy, culture, human health and environmental sustainability in more depth. The low total SEA result shows poor project management and a high safety risk. Finally, the specific managerial measures are proposed to improve the sustainability of infrastructures.
