Abstract: Modern residential structure are going higher and higher these days. The impact of lateral loads in the form of wind/Earthquakes affects the performance of these structures dramatically. It is often a common practice among structural engineers to use shear walls in place of columns. Shear walls are very common in high rise reinforced concrete building. In this study, comparative analysis of high-rise reinforced concrete irregular building with shear walls is present. The frame type of proposed building is used the special RC moment resisting frame. It belongs to seismic zone 2 This is why, seismic forces are essentially considered in the analysis of this building and shear walls are also provided to resist seismic forces. Structural members are designed according to IS456-2000. The structure is analyzed by using ETABS v 9.7.1 software. Load consideration is based on Indian code. All necessary load combinations are considered in shear walls analysis and frame analysis. In addition wind load, seismic load is considered as external lateral load in the dynamic analysis. In dynamic analysis; Response Spectrum method is used. For this purpose four multi storey building plans are considered that are horizontal irregular and vertical irregular models with and without shear walls .All the four buildings were analyzed for zone II. Modal Period with different configuration of building, Storey Displacement of structure with different configuration of building, Storey Drift with different configuration of building were studied and their comparison was done.
