Structural Vulnerability Assessment of Historical Buildings in Turkey
Abstract: Structural
Vulnerability assessment of historical buildings is very important to carry
them to the future. Turkey is a rich country in terms of historic masterships
mostly from Ottoman Empire, such as mosques, bathhouses, churches and
aqueducts. Especially mosques are the common historical structures in turkey.
Therefore, in the present study, structural vulnerability assessment of
historical mosques in Turkey was carried out. One of the existing ones is
considered as a sample building and structural vulnerability assessment was
carried out on this building. The sample building was selected as Konak Mosque
located in Izmir, Turkey. The mosque was structurally investigated through
advanced approaches. The mosque, constructed in 1755 by Ottoman at very central
location close by the clock tower, is little one decorated with blue tiles. The
mosque is also nearby a historical bazaar where the main historical business
stream line is located. Konak Mosque is one of these new styles in that age. It
can be named as a signature historical building representing Islamic minimalist
oriented architecture with its unique octagonal plan. In the present study, the
building was modelled by using the Finite Element Modelling (FEM) software,
SAP2000. Time history analyses were carried out using 10 different ground
motion data. Displacements, base shear and stress values were interpreted and
the results were displayed graphically and discussed. For probabilistic seismic
risk assessment, fragility analyses were also carried out and the fragility
curve and surface were sketched for the mosque. Saddle point was determined on
the fragility surface.
