Eight Seismic And Wind Analysis Of A High Rise Building With Outrigger System At Different Locations Of A Building

Abstract

The development of tall building has been rapidly increasing worldwide by introducing
new challenges that needs to meet through engineering considerations and judgments.
In tall buildings generally lateral loads are often resisted by a system of various types
of shear or core wall. But when the height of the building increases and when some
irregularities present in buildings, the stiffness of building reduced. So the introduction
of outrigger beams and its position in tall buildings with shear walls are used to
provide sufficient lateral stiffness to the structure. This paper is about the behavior of
tall buildings with and without outrigger, its location, optimization and the efficiency
of outrigger irregular tall buildings. Analysis of a 20 storey 3D model of tall building
with outrigger system using ETABS 2016 program is considered in this paper.
