The cities with much higher seismic risk will have to develop new innovative concepts of designing tall structures and an outrigger structural system is one of many such design concepts which have made helped in constructing tall buildings. Outrigger structural system is easy to construct and they provide high lateral stiffness. Further this outrigger system is provided with dampers to improve the efficiency of the structure. This work presents the performance analysis of such outrigger structural system with dampers. Models consisting of one and two outriggers are developed and their performance is analyzed based on their response to dynamic analysis (time history) carried out to the past historical earthquakes in the California region. This work has been carried out using the ETABS software. The parametersdiscussed are lateral displacements, inter-story drifts, shear force and bending moment in the core for dynamic analysis. Also the performance of outrigger structural system with dampers is analysed varying flexural rigidity ratio from 0.25 to 2. From the analysis it is found that there is reduction in responses of the outrigger structure with dampers.
