Abstract: The diagrid structural system has been widely used for tall buildings due to the structural efficiency and aesthetic potential provided by the unique geometric configuration of the system. In present work, concrete diagrid structure is analyzed and compared with conventional concrete building. Structural design of high rise buildings is governed by lateral loads due to wind or earthquake and its resistance is provided by interior structural system or exterior structural system. Due to inclined columns lateral loads are resisted by axial action of the diagonal in diagrid structure compared to bending of vertical columns in conventional building. A regular five storey RCC building with plan size 15 m × 15 m located in seismic zone V is considered for analysis. STAAD. Pro software is used for modelling and analysis of structural members. All structural members are designed as per IS 456:2000 and load combinations of seismic forces are considered as per IS 1893(Part 1): 2002. Comparison of analysis results in terms of storey drift, node to node displacement, bending moment, shear forces, area of reinforcement, and also the economical aspect is presented. Drift in diagrid building is approx. half to that obtained in conventional building. Steel consumed in diagrid building is 33.21 % less as compared to conventional frame.
