Abstract:

The high-rise buildings have been viewed as the landmark of the city with the rapid development of the economy and construction technology. Thus, more high-rise buildings are being built across the world. The Designer of high-rise buildings consider strength, stiffness, stability as an important criterion that are influenced by the lateral loads induced by wind and earthquake. The Lateral stiffness of the building reduces as the height of the building increases. In modern tall buildings, lateral loads induced by wind or earthquake are often resisted by a system of coupled shear walls. To provide sufficient lateral stiffness to the high-rise structures by lateral load resisting system such as outrigger beams which connect the central core and external columns are used. The outrigger with belt truss is used as one of the structural systems to effectively control the excessive drift due to lateral loads. In this paper, an attempt has been made to collect the information from the literature review of research papers related to the analysis of high-rise RC building for outrigger structural system under the action of lateral loads. The objective of this paper is to study the behaviour of outrigger structural system and the effect of disadvantage of column shortening for dynamic analysis under seismic loading.
