Evaluation of Existing Reinforced Concrete Buildings with Structural Package Programs

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.
