Abstract: In contemporary decades, the requirements of the people groups are more for business reason. For that the creating of constructional procedure was enhanced by developing the tall structures. So late tall structures would have more convoluted basic conduct than some time recently. In the event that the stature of the building is goes on expansion while the conduct of the tall building get to be basic as far as straight and non-direct cases. From the thought of basic conduct we need to oppose that basic viewpoints by giving parallel burden opposing frameworks. For the perspective of auxiliary effectiveness and compositional noteworthy give half and half structures by giving the center core at the focal point of the tall structures and diagrid at the fringe of the structures even its disposing of the sections at the border of the tall building. The diagrid framework is just the helpful strategy to give at fringe of a hyperbolic circular about structure since that all floor range are straightly fluctuating to each other, in this manner the vertical sections are not great to give at border of the all floor regions. The motivation behind this paper is to examine the seismic reaction and wind analysis of a hyperbolic circular diagrid structure rehabilitated with shear wall and steel braced frames. Since the hyperbolic circular tall structures are additionally one of the convoluted structure. So in this project we concentrate on the straight static conduct of that specific convoluted structure utilizing programming. In this work basically comprise of two models with shifting floor zone and center divider framework. The external fringe comprise of diagrid funnel segment for both models. These models are examined for two distinctive seismic zones (zone2 and zone3). All the models and its components are investigated utilizing ETABs programming according to Indian codes. This work shows the outcomes parameter regarding story drift, story displacement, time period, story shear and modes
