The aim of this study
is to present a methodology on the determination of the seismic performance of
existing reinforced concrete (RC) structures subjected to earthquake effects.
This paper focuses on the assessment of existing RC structures with a nonlinear
analysis (pushover analysis) method. The research is presented with the case
study of an existing RC structure. The investigations on this RC structure is
done with the field surveys, lab studies and numerical analyses. The first
stage of the study includes the assessment of the compliance between the architectural
and structural design projects of the related structure. Necessary checks have
been made whether the projects of the structure are consistent with its
existing state. Secondly, on-site mechanical tests were conducted on the
structural members and laboratory tests were performed on the samples collected
from the structure. In the last stage, the seismic performance of the structure
was determined based on the three-dimensional finite element model prepared for
the existing state of the structure. The analysis results are discussed
considering the target performance level parameter. The results have shown the
importance of designating the appropriate target performance level in the
evaluation of the seismic performance of RC structures.
