摘要：Tall buildings need a lateral load resisting system to resist the lateral loads induced by wind orearthquake forces. One of the most efficient systems is outrigger. Outriggers are structural systems that supportbuilding against lateral loads. The various parameters like lateral displacement, storey drift, core moment and optimumposition related to outrigger and belt wall are reviewed. The reviewed approach for the design and development of tallbuilding using outrigger and belt wall is useful to provide a potential solution. Recently, outrigger and belt wall systemis widely used to reduce lateral drift. To achieve required stiffness of tall building increase of bracings sizes as well asintroduction of additional lateral load resisting system such as belt truss and outriggers is required. The placement ofoutrigger trusses increases the effective depth of the structure and significantly improves the lateral stiffness underlateral load. Three dimensional modelling for G+45 storey building of concrete is done and the analysis results are takenfor the same. For the seismic analysis zone factor for zone II and medium soil type is considered according to IS: 1893(part1)-2002. Therefore the analysis of wind load can taken from IS: 875 (part 3)-1987. Finally, a relative study of timeperiod according to stiffness was done using software “ETABS v. 16”.
