The seismic performance of high-rise buildings is a critical consideration in structural design due to the destructive nature of earthquakes. Shear walls play a vital role in resisting lateral forces generated by seismic events and winds in multistory structures. While reinforced concrete (RC) and steel shear walls have been commonly used, composite shear walls have gained interest due to their advantages over conventional technologies. Composite shear walls offer cost-effective design, improved structural behavior, and enhanced efficiency in meeting performance and strength requirements. This study focuses on evaluating the seismic effect on high-rise buildings with composite shear walls. The research aims to understand the behavior of these structures using numerical analysis with ETABS 2017 software. Various types of composite shear wall configurations, including double skin composite walls, steel-encased walls, and walls with I-sections, are investigated and compared to traditional RC shear walls. The methodology involves creating building models, defining material properties, incorporating composite shear walls, applying seismic loadings based on design codes, and conducting response spectrum analysis. The structural response parameters, such as displacements, storey drifts, storey shears, and other seismic parameters, are evaluated to assess the performance of the composite shear wall configurations. Sensitivity analysis is performed to understand the influence of parameters such as wall thickness and number of composite shear walls. The study aims to provide insights into the seismic behavior of high-rise buildings with composite shear walls and compare the effectiveness of different configurations. The findings contribute to the development of design criteria and promote the use of composite shear walls in earthquake-resistant structure
