Abstract: Tall building development has been rapidly increasing worldwide introducing new challenges that need to be met through engineering judgment. In Metro cities like Mumbai, Delhi, Chennai, Bengaluru, Kolkata, Hyderabad, Amaravatietc multi-storied buildings are common andpeople are willing to stay in high rise building,the analysis and design of tall building structural system need more concentration than that of regular multi-storied building. The lateral stability of tall building plays an important role in safe analysis and design. the shape of building is not regular like a rectangular (or) square,but they are of the form of Y-shaped and C Shaped buildings. Tall building development has been rapidly increasing worldwide introducing new challenges that need to be met through engineering judgment. In Metro cities like Mumbai, Delhi, Chennai, Bengaluru, Kolkata, Hyderabad, Amaravati etc multi-storied buildings are common andpeople are willing to stay in high rise building,the analysis and design of tall building structural system need more concentration than that of regular multi-storied building. The lateral stability of tall building plays an important role in safe analysis and design. the shape of building is not regular like a rectangular (or) square,but they are of the form of Y-shaped and C Shaped buildings. The target of the present work was to contemplate the utilization of outrigger and belt bracket for RCC frame set at various area’s exposed to wind. The ETABS programming program was chosen to perform the examination of (1) Lateral displacement, (2) Maximum storey drift, (3) Storey shear forces, (4) storey moments and (5) to strengthen the 85 story with story height of 3 meters of RCC building. The building framewas fortified horizontal way by giving Outrigger and Belt support framework at each 9 to 10 story level. Two methods of analysis have been considered for lateral stability analysis viz linear static and linear dynamic for both seismic and wind. The various parameters like (1) Lateral displacement, (2) Maximum storey drift, (3) Storey shear forces, (4) storey moments and (5) Storey overturning moments were considered for better comprehension of Tall building, when it was exposed to substantial seismic and wind powers. The Seismic analysis was carried out according to the Indian measures.
