The advanced construction technologies, evolution of efficient structural system, necessity of vertical growth because of scarcity of urban land and rapidly increasing population caused the development of the high rise buildings all over the world. Lateral loads i.e. earthquake loads and wind loads requires special attention in design of high rise buildings along with gravitational loading. Lateral loads can be taken care by interior structural system or exterior structural system. Generally shear wall core, braced frame and their combination with other frames are interior structural systems where lateral load is borne by centrally located structural elements. While framed tube, braced tube structural system bear lateral loads by the elements provided on periphery of the buildings. It is very much important that the selected structural system must be optimized and should utilize structural elements effectively while satisfying design requirements. In the past decades, the Braced tube structural system is widely adopted and used for the construction of tall steel buildings due to its structural efficiency and aesthetic potential provided by the unique geometric configuration of the system. Compared to closely-spaced vertical columns in framed tube, Braced tube structural system consists of widely spaced column with inclined X- brace members on the exterior surface of building. Due to inclined brace members, lateral loads are resisted by axial action of the diagonals, compared to bending of vertical columns in framed tubular structure. Braced tube structures generally do not require gravity core because lateral shear can be managed by the diagonals on the periphery of building. The aim of study is to decide the best suitable variable pattern of X-Braced pattern under gravity and lateral loading. Analysis of 60,90 and 120 storey braced tube steel structural system is illustrated. Exact analysis using ETABS software* (ETBS’15, a 30 days trial version 2015) is carried out for 60,90 and 120 storey Braced tube building
