Comparative Analysis of Different Lateral Load Resisting System for Geometrically Irregular Shaped High-Rise Building

Abstract

As the population is increasing tremendously with every passing year and the land available for use of habitation is the same as it was a decade ago. So, the only solution to the problem is vertical growth. Now this need for the increase in the vertical height of the buildings has made the buildings tall and slender. Since buildings are getting taller and slender the primary concern of design engineers is shifting from gravity loads to lateral loads. The effect of lateral forces becomes more and more dominant as the building becomes taller and taller. Thus, to boost the performance of the structure under various lateral loading such as in wind or earthquake, lateral load resisting structural system plays very efficient role. In present paper an investigation has been focused on performance of
different lateral load resisting structural system in geometrically irregular shaped high-rise building. Here, in this present work a particular 50 storey C shaped plan irregular building with different lateral load resisting systems are considered and four models are developed in ETABS software with codal provisions. These models are analysed for Static and dynamic behavior. Wind analysis and Response spectrum method is carried out. The Parameters discussed in this paper include Storey Displacement, Storey Drift, Base shear, Base moment, Time period and Torsion for static and dynamic behaviour of different lateral load resisting configurations.
