The design of high-rise building is more often affected by its serviceability rather than the strength of the building. Structural engineers always endeavoring to overcome difficulties of controlling lateral deflection and story drifts additionally self-weight of structure imposed on foundation. One of the most efficient solution is the use of outrigger and belt truss system in composite structure that can solve the described issues in Tall structures. This thesis investigates deflection control by effective utilization of belt truss and outrigger system for 40-storey, 60-storey and 80-storey composite building subjected to Gravity and Earthquake loads. A 3D F.E.M. models have been arranged and analysis have been performed for Different location of outrigger System. Reduction in lateral deflections is compared to a model without Outrigger system. Previous study also shows that outriggers are also capable of reducing the inter story drifts in composite buildings. At the end of Analysis, we found that, by using outrigger and belt truss deflection is reduced, Time period also get reduce which leads to increase in natural frequency of the structure. Graphical representations for Deflection is shown for All different heights of models which are 40-Storey, 60-Storey and 80-Storey.
