Summary:

      In this thesis, the effect of soft story irregularity and torsional irregularity, which are commonly seen in reinforced concrete building, on seismic behavior of a reinforced concrete building was investigated. For this purpose, dynamic analyses of a total number of 54 different structure models of a reinforced concrete building with 3, 6 and 12 floors and ground floors of 3.0 m, 4.0 m and 5.0 m heights were performed by using SAP2000. Within the first chapter of this study being composed of four main chapters, after principles of seismic resistant building design are underlined briefly, some studies performed earlier related to subject are presented. In the second chapter, dynamic analyses to calculate soft story irregularity and the coefficients of torsional irregularity for the subject of study reinforced concrete buildings under vertical loading are performed. In the third chapter, findings obtained from those analyses are discussed and relation between irregularity cases of the studied subject are attempted to be expressed. In the fourth chapter where all conclusions and recommendations derived from this study is presented followed by curriculum vitae and references.

As a result of this study, it is concluded that the soft story irregularity, which is defined as the rigidity irregularity between adjacent floors in the analyzed frame type reinforced concrete building, is directly related to the presence of masonry wall and the presence of masonry walls has no significant effect on the formation of torsional irregularity.
