Design and Detailing of G+8 Shear Walled RCC Framed Structure Suhail Raza1, Prashant Vashisht2 1Student of Bachelor of Technology in Civil Engineering, Lingaya’s Vidyapeeth, Faridabad, India 2Assistant Professor, Lingaya’s Vidyapeeth, Faridabad, India
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - This paper presents the design and detailing of a G+8 reinforced cement concrete (RCC) framed structure with and without shear walls using STAAD Pro software. The structure is located in Delhi, India, with a height of 27 meters, using concrete grade M25 and steel grade Fe415. The study focuses on the comparative performance of the structure under lateral loads due to seismic activity in Delhi's seismic zone (Zone IV). A comparative analysis is performed with respect to base shear, deflection, and risk assessment using both tabular and graphical representations. Key Words: Size G+8 RCC Structure, Shear Walls, STAAD Pro, Seismic Analysis, Base Shear, Structural Performance, Risk Assessment.
1. INTRODUCTION Earthquake Zoning of India India has a history of major earthquakes. The main reason for the high frequency of earthquakes is that the Indian plate is moving towards Asia at a rate of 47 millimetres per year. Geographical analysis of India shows that about 54% of the land is vulnerable to earthquakes. According to World Bank and United Nations reports, about 200 million urban dwellers in India are expected to be affected by storms and earthquakes by 2050. The latest version of the seismic zoning map of India given in the Indian Seismic Design Code [IS 1893 (Part 1) 2002] has divided India into four seismic levels based on regional factors. In other words, the seismic zoning map of India divides India into 4 seismic zones (Zones II, III, IV and V) as opposed to the earlier version where the seismic zoning of India had V to VI zones. According to the current zoning map, Zone V has the highest level of seismic activity, while Zone II has the lowest.

2. BUILDING CONFIGURATION AND DESIGN PARAMETERS 2.1 Shear Wall Shear walls are designed to resist wind and seismic loads. Shear walls are designed by the International Building Code and the International Residential Code. The plane of the wall is parallel to the shear walls. The shear walls and other vertical elements of the system are resistible because of the Collectors. Shear walls used in the study analysis consists of reinforced concrete walls.
This Delhi, being in Seismic Zone IV, is prone to moderate to high seismic activity. The structural design of high-rise buildings needs to address the safety concerns caused by seismic forces. Shear walls are used to provide additional stiffness to resist lateral forces, improving the overall stability of the building. In this study, the structure is analysed with and without shear walls to understand the effect of these elements on the stability of an RCC framed structure.
