Abstract
Recent years have witnessed the rapid development of high rise structures/buildings. Construction of tall structures has introduced new challenges to the structural engineers. Along with gravity loads the most critical loading for tall structures are proved to be lateral loads i.e., wind and seismic loads. With the increase in the height of building the different structural systems are developed
correspondingly. In respect of reducing or minimizing the risk of structure, the outrigger is used is as the structural system to reduce the displacement and drifts. The major objective of this thesis is to study the behavior and optimum alignment of outrigger systems with and without belt trusses of a 30-storey three dimensional model subjected to lateral loads. The analysis has been carried out in Etabs 2015 version software for models with different alignment of outriggers. The outcomes have shown that the outriggers system has a considerable effect in minimizing of lateral displacement and storey drift of tall structures
