Today, ground or basement floors of buildings
are designed as soft floors for use as parking lots and workplaces. Therefore, the soft story of the structure under
the effect of earthquake may show non-ductile behavior. In this study, a number of approaches have been
proposed to improve the behavior of the soft story and ensure its usability. In order to eliminate the negative effects of
the soft story, passive isolation systems were preferred as well as the use of
central and external central braces. A computer-based Matlab program was used to
understand the behavior of the structure in the frequency domain, and a finite
element program was used to perform the related analysis. According to the analysis results, it has been
determined that the use of the central and external center improves the
behavior of the structure in appropriate frequency ranges, but the use of
passive isolator systems is not suitable for the relevant structure. It has been confirmed that the passive isolators
should be designed according to each structure and any possible earthquake
feature.
