various structural systems, including Reinforced Concrete (RC) frames, shear walls, bracing systems, and outrigger systems, to assess their seismic performance as per IS 1893: 2016. The evaluation is conducted across seismic zones II, III, IV, and V to determine the efficiency of these systems in resisting earthquake-induced forces. Key parameters such as base shear, inter-story drift, and lateral displacement are analyzed using static and dynamic methods to assess the behavior of each structural system under different seismic intensities. The findings highlight the strengths and limitations of each system, offering critical insights to aid in selecting appropriate structural solutions for enhanced seismic safety and performance across varying zones.
1.1 Structural Systems Overview. Moment-Resisting Frames: Moment-Resisting Frames are structural systems that rely on rigid beam-column connections to resist lateral forces through bending, offering significant ductility to absorb seismic energy. They enable open floor plans, providing flexibility in architectural design. Classified into Ordinary, Intermediate, and Special Moment Frames based on ductility and seismic performance, they are widely used in earthquake-prone regions. However, these frames can be costly and complex to construct and may sustain damage during severe earthquakes. Modern advancements like seismic isolation and damping systems are increasingly integrated to enhance their resilience and efficiency.
Key Words: Seismic performance, structural systems, RC frames, shear walls, bracing systems, lateral displacement, earthquake resistance.
1.INTRODUCTION Seismic design has evolved significantly over time, driven by a deeper understanding of earthquake dynamics and the need for resilient structures. In India, traditional construction methods provided some resistance to seismic forces, but modern approaches have brought systematic improvements. Historical architecture, such as temples and forts, showcased durability through massive and solid designs, albeit without explicit seismic principles. Early construction relied on empirical methods until modernization highlighted the need for structured seismic design, leading to the adoption of global standards and localized strategies.

They are categorized into reinforced concrete, masonry, and composite shear walls. Renowned for their excellent lateral stability and efficiency in tall buildings, they offer a costeffective solution when designed properly. However, shear walls can limit floor plan flexibility and demand precise construction techniques. Modern innovations emphasize the use of high-performance materials and advanced designs to enhance their strength and adaptability.
Major earthquakes have been pivotal in shaping India's seismic design practices. The 1934 Bihar-Nepal Earthquake (magnitude 8.0) underscored the need for robust engineering in vulnerable regions. The 1967 Shillong Earthquake (magnitude 6.7) emphasized seismic considerations in northeastern India. The devastating 2001 Gujarat Earthquake (magnitude 7.7) spurred a comprehensive overhaul of design codes, including stricter enforcement of regulations and updates to standards like IS 1893. These events have driven the evolution of seismic
