Structural irregularity may be classified as in- plan and in-elevation. In this study, vertical irregularities are in consideration since less research has been done compared to the in-plan irregularities. Vertical irregularities designated in buildings are due to many reasons such as mass, stiffness and strength irregularity and the dynamic behavior of the structures are totally related with those three parameters. Previous researchers focused on mostly strength and stiffness properties of the models employed. In practice, infill walls may become one of the reasons of vertical irregularity resulting in the soft story and short column. Misapplication or architectural aesthetics may result in unexpected failures at story columns due to short column effects. On the other hand, recent studies and seismic performance of RC buildings from recent earthquakes showed that infill walls have a significant effect on the strength capacity of the building and should be modeled in analysis and design. To be able to investigate the effect of vertical irregularities due to Infill walls, i.e. soft story effect, a reliable and accurate infill wall model that simplifies modeling and decreases computational effort is needed. Thus, the most appropriate modeling approach for infill walls will be investigated to be able to get reasonably good and accurate results from the numerical models. In this study ASCE, 41 strut methodology is compared with experimental results and is modified for future studies. OpenSEES is used for modeling and comparison of the numerical models with experiments. Vertical irregularities are assigned to the regular frames based on stiffness and strength change. Computed demands are compared with the design parameters defined in IBC (International Building Code) and TEC 2007 (Turkish Earthquake Code).
