There has been a considerable increase in modern tall buildings due to the development in construction technology and structural systems. As the building height increase, lateral loads are important consideration and it is necessary to choose a structural system that can resist lateral load effectively. Lateral loads are often resisted by various lateral load resisting systems: Beam-Column System, Shear Wall and Frame System, Frame Tube System, Dia-grid System, Dual System, etc…..In this paper, a particular type of 16-storey Irregular-shaped RC building in Zone IIA is considered with different lateral load resisting systems (i.e – Beam-Column System, Rigid Frame with Shear Wall and Dual System). Modelling and Analysis of building with different load resisting systems are carried out with ETABS V 9.7.4 software. Structural members are designed according to ACI code 318-99 and load consideration is based on UBC-97. In dynamic analysis, Response Spectrum Method is used. The values of stability check such as storey drift, P-? effect, Overturning, Sliding in each system are compared. Since the building is irregular-shaped, torsional irregularity is also considered and soft storey and base shear are also check. All this points are considered and the results obtained are plotted and compared with graphs. This paper give information about various lateral load resisting systems and dual system gives better performance than other with same material consumption of lateral load resisting systems.
