Assessment of medium ductility low rise reinforced concrete building in high seismicity region

Abstract

The aim of this study is to investigate the response of regular and irregular in elevation on medium ductility low rise reinforcement concrete buildings located at high seismicity region. Two families of reinforcement concrete frames were designed and examined. The first set of frames known as Frame A is regular in elevation frames while the second set known as Frame is irregular in elevation frames. Both sets of frames were designed in accordance with the requirement of Eurocode 2 and Eurocode 8. A basic Push Over Analysis was employed to examine all these frames. Based on capacity curve, the ductility factors and overstrength factors were discussed. The differences in terms of the responses and geometry of these two sets of frames are significant. It is found that Eurocode 8 frames have higher ductility factor compared to Eurocode 2 frames. Other than that, the cross sections for beams and columns of Eurocode 8 frames are bigger than those in Eurocode 2 frames. Besides that, it is found that the overstrength factors for Eurocode 8 frames are lower than the Eurocode 2 frames.
