Abstract - This paper examines the design and detailing
of a Ground Floor + 8-story Reinforced Cement Concrete (RCC) framed structure located at Okhla NSIC, New Delhi. The structure, with a height of 24 meters, is analyzed with and without shear walls using ETABS software. Key parameters include concrete grade M20, reinforcement grade Fe415, stiff soil type, minimum base shear of 1323.1 kN, and design base shear of 4162.58 kN. The study evaluates seismic performance, risk assessment, and construction methodologies. Tables and graphs illustrate findings on structural performance and safety. The research emphasizes the importance of shear walls in enhancing seismic resistance.
Seismic activity poses significant challenges to building stability, particularly in regions like New Delhi, categorized under Seismic Zone IV. Shear walls, as integral components of lateral force-resisting systems, play a critical role in mitigating seismic damage in RCC structures. This study compares the performance of a G+8 RCC framed structure with and without shear walls. Using ETABS software, the paper explores structural behavior, base shear, story drift, and stiffness to assess the impact of shear walls.
Key Words: Concrete grade M20, Reinforcement grade Fe415, Stiff Soil type, Minimum base shear and design base shear.
2. SHEAR WALLS Definition: Shear walls are vertical structural elements designed to resist lateral forces caused by wind and earthquakes. They are crucial in high-rise buildings, providing stiffness and stability.
1. INTRODUCTION Earthquake zoning in India refers to the division of the country into regions based on their vulnerability to seismic activity. This classification helps in understanding the potential risk of earthquakes in different areas and guides the development of appropriate construction standards and disaster management strategies.
Functions:
India's zoning system categorizes the country into four seismic zones: Zone II, Zone III, Zone IV, and Zone V, with Zone II having the lowest seismic risk and Zone V the highest. This classification is based on historical earthquake data, tectonic features, and the intensity of ground shaking experienced in various regions.
Placement: Shear walls are strategically located around staircases, elevator cores, and external walls for optimal performance without compromising architectural design.
3. SEISMIC ZONES OF INDIA
Zone V includes areas like the northeastern states, parts of Jammu and Kashmir, Himachal Pradesh, Uttarakhand, and the Andaman and Nicobar Islands, which are highly prone to severe earthquakes. Zones IV and III encompass areas with moderate to significant seismic risk, while Zone II covers regions with relatively low seismic activity.

Resist lateral loads. Minimize inter-story drift. Enhance overall structural rigidity.
India’s seismic zoning is classified into four zones based on earthquake intensity:
|
Zone II: Low-intensity earthquakes. Zone III: Moderate-intensity earthquakes. Zone IV: Severe-intensity earthquakes (e.g., Delhi).
