Abstract:
This study investigates the effects of outrigger systems to the functionality of a structure that has a tube system during wind and earthquake loads. In the high-rise buildings and especially the tube structure, the building is on the rise and is exposed to the environmental loading thus exerting dynamic forces. The outrigger is a structural component, which is normally installed at higher levels, and this has been identified to contribute to the lateral stability and hardness of high-rise buildings. Nevertheless, its relationship with the tube system in the combined wind seismic forces has not been all researched. In this study, parametric analysis is carried out extensively by the use of elaborate computational models to model the behavior of buildings with a tube system supported by outriggers at various loading conditions. The study analyzes the efficacy of outriggers to minimize the displacement, torsional and the overall seismic and wind resistance of the structure. Outrigger placement configurations, stiffness and structural integration with the tube system are also examined in different combinations to determine the combined effect on the performance of the building. The findings indicate that outriggers do help in enhancing the lateral stability of the structure and its stiffness particularly during the times of wind and earthquake forces. Structural loading, minimization of sway and minimization of structural damage are demonstrated to be improved by the best location and design of outriggers. This study gives a major contribution to the design of high rises, which provides the engineer with an understanding of how to better the outrigger systems in tube types of structures to be in a better position to withstand the dynamic forces within the environment.
