Review on Comparative Analysis of Outrigger Braced System with Different Lateral Load Resisting System in Multistorey

The advancements in engineering and technology, development of high strength structural materials, rise in population and lack of land area available due to the increase in land prices and rapid urbanization have led to the development of high-rise buildings in the modern era. The high-rise buildings are the most susceptible to the lateral loadings due to the wind and seismic forces. The trend of taller and slender structures makes it necessary to develop the structural system which can resist the lateral loads effectively with minimum cost. In this study we compared two lateral load resisting system for dynamic analysis of flat slab multistory building one system is outrigger bracing system and other is Shear wall system. The outrigger bracing system provides the solution to control excessive drift and displacement in high rise buildings. It consists of the outrigger bracings or the outrigger trusses which connects the central core of the building with the peripheral columns and the peripheral columns relate to one another through the belt trusses. The studies afford the precis of different research work & conclude with identified gaps in the research in addition to recognize the object of required work.
