Recently, the number of tall buildings being constructed has been rapidly increasing worldwide. Some buildings have been
constructed with triangular exterior structural members, exterior frame structural members, tube structures, etc. Different
structural systems like Exo-skeleton structural system, diagrid structural system, etc are adopted in recent development. Tall
building structure is adopted for its structural efficiency. Exoskeleton structure consists of lateral load resisting systems in the
category of exterior structures. An exoskeleton structure consists of independent and lateral load resisting sub systems. In diagrid
structure, it consists of inclined columns on the exterior surface of building, compared to closely spaced vertical column in framed
tube. Analysis of Exoskeleton structural system, diagrid structural system and conventional structural system for 24 storey
building is presented here. A regular floor plan of 36 m × 36 m size is considered for all structures. ETABS software is used for
modelling and analysis of structural members. All structural members are considered as per IS 800:2007 considering all load
combinations. Dynamic along wind and across wind are considered for analysis of the structure. Comparison of analysis results
in terms of time period, storey displacement, storey shear and storey drift with conventional building is presented in this paper.
