Finite-Element Model Calibration of Historical Masonry Domes Using Operational Modal Testings
Publication: Journal of Performance of Constructed Facilities
Volume 30, Issue 2
Abstract
This paper aims to determine the dynamic characteristics, such as natural frequencies, mode shapes and damping ratios, of two different domed structures, namely Hamza Paşa Mausoleum and Kavak Meydan Fountain, built in the sixteenth century by experimental methods. The experimental dynamic characteristics are used to develop initial analytical models and update these models. Analytical models of the structures are constituted using finite element theoretical software, and dynamic characteristics are determined analytically. The experimental measurements are carried out by operational modal testing under environmental loads, which are wind and traffic loads, and the dynamic characteristics are identified experimentally. Vibration responses are collected from the dome’s outer surface for Hamza Paşa Mausoleum and the dome pulley’s inner surface for Kavak Meydan Fountain. Measurement time, frequency span, and effective mode number are determined by considering pretest measurement results. At the end of the study, analytical and experimental dynamic characteristics are compared with each other and the finite element models of these domed structures are updated by changing material properties and boundary conditions.
