| Zusammenfassung |
| Engineering structures strengthened with FRP composites are gaining
popularity, and there is a growing need to understand and compare the
behavior of these structures before/after FRP composite strengthening. In
this paper, it is aimed to determine the dynamic response of masonry
minarets before/after FRP composite strengthening. An Iskenderpaşa historical
masonry minaret dating back to XVI century with a height of 21 m located in
Trabzon, Turkey was selected as an application. Firstly, 3-D finite element
model of the minaret was constituted using ANSYS software. Then, an analytical
model of the minaret was analyzed using the 1992 Erzincan earthquake record,
which occurred near the area, to determine the dynamic behavior. After this,
the cylindrical body of the minaret was strengthened with FRP composite using
different configurations and dynamic analyses were performed. Finally, dynamic
responses of the minaret before and after FRP composite strengthening, such as
displacements and maximum-minimum principal stresses, were compared. At the
end of the study, it is seen that displacements had increased along
the height of the minaret, maximum and minimum principal stresses occur at
the region of transition segment and cylindrical body for all analyses.
Also, it is seen from the earthquake analyses that FRP strengthening is very
effective on the dynamic responses of the minaret. |
