Abstract
The study presents to determine the seismic
performance of an existing hictorical masonry school building. Within the scope
of the study, the C block of the building which consists of three blocks, was
examined. In this scope, initially, field investigations including material and
damage situations is performed regarding the examined building. After that, the
mechanical properties of the masonry structural members are determined
according to the relevant codes. The soil characteristics are obtained from the
soil classification map prepared by the Istanbul Metropolitan Municipality, and
seismic parameters are determined considering the location of the building and regional
seismic risk map. In the next step, the structural model is prepared to
represent the existing state of the structure by Midas Gen software, and the
performance analysis is performed using the linear elastic analysis method. The
response spectrum analysis method was chosen to consider the contributions of
different modes. As a result of the school building being a historical
structure, the seismic performance assessment was based on “Guidelines for the
Management of Earthquake Risks in Historical Buildings of 2017”. The importance
level and performance target of the building was decided by the local
administration. Earthquake loads are calculated according to Turkey Building
Earthquake Code 2018 and was considered in the structural model. As a result of
analysis, it is determined that the current status of C block not provided
“Controlled Damage” performance level for DD-2 Earthquake Ground Motion Level
for an earthquake with a 10% probability of exceedance in 50 years”. The
strength and displacements of the masonry walls in this block were obtained
beyond the limit values given for the target performance level.
