Abstract

Earthquakes are most devastating natural hazards in terms of life and property of any region. The behavior of the structure greatly depends on size, shape and geometry of that structure in addition to how the earthquake forces are carried to the supporting ground. Irregularity in building attracts orces which lead to stress concentration at the point of irregularity; subsequently it leads to localized failure of that structure. The present study focuses on seismic performance of irregular RC frames in elevation. For this purpose ETABS a finite element software has been used. Here 2-D RC frames with four bays are considered. The irregularity is gradually increased from regular frame to highly irregular frame. Roof displacement; Base shear carried; performance points; number of hinges formed are the parameters used to quantify the performance of the structure
