Determination of Modal Parameters of Historical Masonry Minarets by using Operational Modal Analysis
Bibliographic record
Abstract
This study conducted to investigation of modal parameters (such as mode shapes, modal frequencies ) of a masonry type historical minaret by performing numerical and experimental analys es. Operational Modal Analysis (OMA) Technique is used for experimental study to obtain modal parameters of historical masonry minarets. For this purpose, Byk Mosque located in Samsun, Turkey, was chosen for the experimental analysis. The Frequency Domain Decomposition (FDD) method is utilized to identify the natural frequencies and mode shapes experimentally. ANSYS software is used to carry out 3D finite element modelling of the historical masonry minaret and determine the natural frequencies and mode shapes of the minaret analytically. Furthermore, the finite element model of the minaret is calibrated according to the experimental results by using t he Response Surface based finite element (FE) model calibration technique to obtain more accurate results of the modal parameters of the structure. The results of experimental, initial and calibrated finite element model were compared to each other. It can be noticed significant differences when comparing the results of the experimental and analytical with the initial conditions. Model calibration techniques are necessary to obtain more reasonable finite element model.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
