Abstract: High rise structures are more vulnerable to earthquake loads. Hence to build this high rise structures stable an external frame works is required to increase its resistance against the seismic tremor one of such system is the belt truss systems. In this study, the response of steel tubular structures with and without the belt truss systems subjected to earthquake forces is evaluated under the seismic zone V considering 70 storey steel tubular structures for analysis. The analytical method used in this dissertation work is Time History Method. Time history analysis is performed by using BHUJ earthquake data. The software utilized for the analysis is ETABS v 9.7.4. Also, the location of belt truss in the tube in tube and framed tube structures and comparison of these steel tubular structures with the steel moment resisting frames are carried out. In this work, various parameters like storey drifts, storey displacements, time period and base shear has been evaluated for different models and have been compared to obtain an efficient structure
