    "description": "<p>In high rise buildings or multi story buildings, soft-story construction is common because of story height difference due to architectural consideration. These provide stiffness irregularities on the building structures, which reduce the stiffness of the lateral load resisting system and sudden reduction in stiffness causes higher stress to be concentrated at the stiffness reduced story columns, which lead the columns to be unable to provide adequate resistance during the earth quake.<br>\nTaking into consideration the above points, the structural building frames must be evaluated and designed by considering the effect of soft story on seismic performance of the building. The main focus of this research is to study the seismic performance of stiffness irregular building due to significant story height difference on RC buildings by implementing numerical models on the basis of finite element principles. For these two regular buildings G+10 and G+20 is developed to be considered as base case structure, and cases that represent irregular structures are defined by modifying vertical distribution stiffness of the base case. The stiffness irregularity is created by increasing the height of ground floor and second floor of base case 200%. Accordingly, different model cases of RC building are analyzed and designed on ETABS 2016.2.1 (CSI ETABS 2016, Integrated Building Design Software, Computers and Structures Inc. Berkeley).</p>",
