“…Actual earthquake ground motions observed during the 1995 Hyogo-ken Nanbu earthquake were used in their study in conjunction with impulse waves to determine the modal characteristics and their collapse potential. B. Sevim and co-workers [5] conducted studies of arch bridges in Turkey where ambient vibration data were utilized to calibrate numerical models which subsequently were used to conduct linear earthquake analyses and assess the behavior of the bridges resulting from the excitation by the 1992 Erzincan Earthquake and address the importance of the model calibration process guided by actual field data. Numerical studies on the seismic behavior of the Konitsa Bridge (on the Aoos River near the city of Konitsa) which was build based on same principles and around the same time with Plaka Bridge were recently performed [6].…”

The collapse of the historic Plaka Stone Bridge due to extreme flooding and in particular the pinpointing of the causes or possibly weak structural points that led to the structural failure is studied using high fidelity, three-dimensional non-linear numerical analysis and sensitivity studies. Specifically, the potential of a number of postulated scenarios in initiating failure and leading to the eventual collapse of the bridge are explored aided by sensitivity analyses relying on non-linear finite element modelling and is augmented by actual material properties of the structural elements deduced from laboratory tests following the collapse (i.e. stone and mortar). Presented in detail is the scenario which appears to closely replicate the mode of actual bridge failure observed (damage extend and debris distribution) and deemed by the authors to be most likely sequence of events that occurred. This scenario postulates the undermining of the central pier by support or shear section failure leading to large deformation and displacements on the lower part of the pier eventually leading to shear failure of the primary arch. Based on the failure mode predicted by simulation and corroborated with observed damage the vulnerability of the Plaka Bridge to this "beyond design basis event" even for an uncompromised structure is assessed by asking the question whether any preventive maintenance and upkeep could have saved this particular bridge or that its collapse was beyond human intervention.

“…It was reported that an average natural frequency error was decreased from 15 % to 5 % with modal calibration [2]. Moreover, it was underlined in the same paper that higher maximum and minimum principal stress values were obtained before modal calibration [2]. Atamtürktür [9] investigated the model structure error due to simplification of complex geometry, and the model order error due to discretization of system during creation of mesh.…”

“…Improving correlation between the FE simulation and experimental model using available measured data is known as model calibration or updating [1]. The aim of model calibration is to improve certainty of engineering properties of the FE model and to bring modelling assumptions of a specific FE model as close as possible to reality [2]. In other words, the main purpose of model calibration is to bypass unforeseen aspects related to modelling [3].…”

“…A cross validation method was used to eliminate incomplete modal data, and the authors concluded that the modal updating process was implemented successfully, with less than 1 % of error. Sevim et al [2] used modal calibration to eliminate the model parameter error in a historical masonry arch bridge to obtain correct structural analysis results. It was reported that an average natural frequency error was decreased from 15 % to 5 % with modal calibration [2].…”

An adaptive solution for updating structural model of a RC structure with two-leaf cavity brick infill wall under flexible boundary problem is presented in this paper. The structure was simulated with Diana 9.4.4 finite element software. Next, an elastic foundation with interface elements was used to overcome this stiffness problem of the foundation. The validation of the structure was made with the optimization based modal updating using MATLAB. Five calibration types were performed and compared with experimental data. Deterministički pristup za kalibriranje modela ab konstrukcije s dvoslojnim šupljim zidom od opeke U radu je prikazano prilagodljivo rješenje za kalibraciju modela AB konstrukcije s dvoslojnim šupljim zidom od opeke u svrhu rješavanja problema popustljivih rubnih uvjeta. Simulacija konstrukcije provedena je pomoću programa Diana 9.4.4 koji se temelji na metodi konačnih elemenata. Kako bi se uklonio problem krutosti u temeljima, usvojeni su elastični temelji s kontaktnim elementima. Provjera konstrukcije obavljena je modalnim kalibriranjem baziranim na optimalizaciji pomoću programa MATLAB. Analizirano je pet kalibracijskih tipova, a dobiveni su rezultati te uspoređeni s eksperimentalnim podacima.
