Throughout human
history, the need for shelter has been tried to be met with different structure
materials, taking into account both economic conditions and security. The
so-called “Hımış” houses formed by filling the gaps between the timber frames
with masonry elements reflect the typical features of the Ottoman city
structure. The aim of this study is to determine numerically and experimentally
with Experimental Modal Analysis the dynamic characteristics of the historical
hımış mansion in Fındıklı district, Rize province of Turkey. Although it
requires micro-modeling for the hımış structure, macro modeling was preferred
considering the analysis time and the complexity of the structure. The
important part is to transfer the material properties of the micro model to
macro modeling. Especially when material tests are not possible, matching
material properties should be selected for macro modeling, and these values
should really reflect the current state of the structure. In this study, micro
and macro models for only one wall of the Hımış mansion are created with the
ANSYS software. Modal analysis is applied to both walls and material properties
for macro model are updated until the modal parameters are same. Conjugate
material values obtained by macro modeling are applied to the whole structure. The
numerical modal parameters of the model whose material properties were
determined, were compared with the existing experimental modal parameters of
the building. The spring constants defined as the support condition have been
updated by considering the experimental modal analysis results. The
compatibility of the results with each other shows the accuracy of the selected
conjugate material values. Thus, the finite element model representing the
historical mansion was obtained as a result of the operations applied.
