Abstract:
Seismic performances of the structures shall be investigated due to lack of strength,
seismic forces and change of intended purpose. Package softwares are developed to perform the
complicated performance analyses easily. However, engineers must investigate the efficiency of
these softwares. In this study, three different packaged softwares are used to compare the linear
performance analyses according to Turkish Seismic Code-2007. Since non-linear performance
analysis methods are not available in all programs, it is not taken into consideration in the scope
of this study.
Linear performance analysis of five different reinforced concrete (R/C) structures such as
column-beam frame systems and systems with shear walls are analyzed and seismic
performances are obtained. Furthermore, performance values are inclusively compared with
figures. The reasons of the differences are presented. With the analyses, r values differ from each
other. The main reason of this situation is the difference in remnant moment and efficient
moment values. Modeling techniques also affect this case. According to the results, seismic
performances of structures that have basic geometry, small sections and less irregularities are
close each other. On the other hand, the results become different with the irregularity. Especially,
seismic performances of the structures with shear walls differ from each other due to the various
acceptances.
