Abstract

The evolution of tall building has been enlarging worldwide and brings up various challenges. When building height increases, the stiffness of the structure largely reduces. For lateral load resisting outrigger system is very much effective to control the lateral Drift. Thus, to boost the performance of the structure under various lateral loading such as in wind or earthquake outrigger structural system plays very efficient role. In present paper an investigation has been focused on performance of dual outrigger structural system in geometrically irregular shaped building. Static and dynamic behavior of 60 storey irregular shaped building with different outrigger configurations was analysed by using ETABS Software. Wind analysis and Response spectrum method was 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 outrigger configurations.
