prevalent in urban areas due to land scarcity and population growth. These tall structures pose unique design challenges, making their analysis crucial for ensuring structural safety and resilience against various loading conditions, including seismic events. This study focuses on the analysis of a G+21 residential high-rise building using the ETABS software, a powerful tool for structural analysis and design. The primary objective is to conduct both static and dynamic analyses, evaluating the building's performance under different seismic zones (II, III, IV, and V) as per the Indian Standard IS 1893. By considering multiple seismic zones, the study aims to provide a comprehensive understanding of the building's behavior under varying seismic intensities. Static analysis involves determining the building's response to gravitational and lateral loads, while dynamic analysis considers the structure's dynamic characteristics and time-varying nature of seismic forces. The results obtained from both analyses will be compared, allowing for a thorough assessment of the building's performance and identification of critical design considerations. Key Words: High-rise building, ETABS, static analysis, dynamic analysis, seismic analysis, IS 1893, seismic zones, response spectrum analysis.

1.INTRODUCTION
1.1 Objective
High-rise buildings, towering structures that redefine urban skylines, necessitate meticulous engineering and design to ensure safety and functionality. These structures, typically exceeding 75 feet in height, require specialized structural systems to withstand vertical and lateral forces while accommodating various functionalities such as residential, commercial, and mixed-use spaces.
i. To check & analysis of the seismic response of multistoried building using E-tabs. ii. To Evaluate the structural integrity and safety of the high-rise building under various loading conditions, including dead loads, live loads, and seismic loads, in accordance with relevant building codes and standards.
ETABS (CSI), emerges as a paramount tool in the realm of structural engineering. This innovative software simplifies the complexities of structural design, ensuring safety, resilience, and efficiency. Its comprehensive capabilities have revolutionized structural analysis and design practices, shaping modern construction landscapes worldwide.
iii. Optimize the structural analysis to achieve cost-effective and efficient use of materials while maintaining structural safety and performance. iv. Offer recommendations for design improvements, strengthening measures, or alterations to enhance the building's resilience and safety.
Understanding seismic hazards is crucial in construction, especially in seismically active regions like India. The Bureau of Indian Standards (BIS) classifies India into seismic zones
