The rapid growth of urban population and limitation of available land, the taller structures are preferable nowadays. So when the height of structure increases then the consideration of lateral load is very much important. For that the lateral load resisting system becomes more important than the structural system that resists the gravitational loads in this era, there is rapid increasing in construction of high rise building all over the world. Development of building types, forms, spans, construction technology, analysis and design software ease the growth of the high rise building. So when the height of structure is increases then the consideration of lateral force is become vital. The major problem of tall buildings now-a days is the displacement and drift parameters which causes problems for the people accommodating at the top story, to prevent such problems different structural systems are analyzed to minimize top story displacement. To solve the above- mentioned problem the use of diagrid structure system shall be beneficial to mitigate the displacement to a particular limit. Till now the study of diagrid system was limited the square and rectangular shaped tall building with or without irregularity. In present study comparison of structural performance is made to understand the behavior of two differently planned 30 -storey diagrid structures. Hexagonal and Octagonal plan diagrid structural performance is evaluated for two important loadings viz. earthquake and wind loading. ETABS software is used for analyzing the models subjected to gravity, wind and seismic forces with appropriate load combinations all structural members are designed as per IS 800:2007 considering all load combination. The angle of diagrid provided is 71 for Hexagonal and Octagonal model. The comparison of results in terms of storey drift, top-storey displacement, time period, base shear is presented here and optimal diagrid angle for Hexagonal and Octagonal diagrid structure. Diagrid structural system is found to more profound when architectural arrangements are considered due to the application different diagrid angle which doesn’t disturbs the design and geometry of building and due to its unique structural arrangement we can design building of various shaped for e.g., square, cylindrical, rectangular etc. and the lateral displacement is found to be very less due to the application of diagrid to the tall structures.
