Abstract: In present scenario, the construction industry required high-rise and lighter structures, as tall and lighter structures are having more flexibility and small damping value so that it is less efficient to resist seismic responses. They are more susceptible to failure possibilities, LFRS to be provided to the tall structure which will results in reduction in the vibration induced by seismic and wind actions. Lateral Force Resisting System is big, heavy piece, which is constructed or installed from bottom to top of the tall structure and at different locations of the tall structure in plan and elevation. LFRS is either shear wall or bracing or combination of Shear Wall and Bracing. LFRS is installed in the tall RCC structures at various suitable locations. This research work concerned with controlling the tall RCC structural seismic effect by using lateral force resisting system (LFRS). LFRS are arranged in combinations and attached at different locations in the building. To study the seismic behaviour of tall lateral load resisting structure by taking either shear wall or bracing or combination of Shear Wall and Bracing using Response Spectrum Analysis method on ETABS v17.0.1 software. From this study the result obtained to find most effective arrangement on the basis of seismic parameters (time period, base shear distribution, max. storey displacement, storey drift & storey stiffness) and find out best suitable arrangement at given condition.
