elements. The project involves creating a detailed multistorey building model in ETABS, exploring symmetric and asymmetric configurations, and subjecting the structure to diverse loads for testing. The analysis covers key structural aspects, including displacements, bending moments, shear forces, and internal stresses. A comparative study is conducted between conventional slabs, known for their simplicity and cost-effectiveness, and grid slabs, which enhance structural efficiency through the use of a grid of beams. Grid slabs offer advantages such as reduced material usage, longer spans, and improved load-bearing capacity. The primary objective is to assess and compare the structural performance of conventional and grid slabs, with a specific focus on displacements, member forces, and overall structural efficiency. The research also extends to evaluating each slab type's performance under varying loading scenarios. Based on the analysis results, the project proceeds to design structural elements like columns, beams, and slabs in compliance with relevant building codes and standards, ensuring structural integrity and safety. In conclusion, the project's findings aim to provide valuable insights into the comparative performance of conventional slabs and grid slabs in multi-storey buildings. This information is intended to assist engineers and architects in making informed decisions when selecting suitable slab systems for diverse building layouts.
The objective of the project is to investigate and compare the structural effectiveness of two categories of floor structures in multi-story constructions: traditional slabs and grid slabs. Utilizing the ETABS software, an in-depth analysis and design procedure will be executed to evaluate their operational efficiency. The study will encompass both symmetric and asymmetric building configurations to examine the response of these slabs under diverse structural conditions. Essential elements such as gravitational forces, lateral loads, and seismic forces will be meticulously taken into account during the building's design phase. ETABS offers robust tools for simulating and assessing building performance under these forces. The project involves the creation of a multi-story building model in ETABS, with a comprehensive examination and comparison of deflections, moments, shears, and stresses for both types of slabs. The primary focus is on appraising their structural efficacy and effectiveness. Various loading scenarios will be taken into consideration to assess the performance of each slab type. Additionally, the design of structural elements will adhere to building codes and standards to guarantee safety and stability.

The literature is reviewed from various sources includes books, journals, notes, video lectures, codes etc. The standards are established by the Bureau of Indian Standards (BIS) are fundamental in the assessment of the forces acting upon structures. In our research, we have utilized the Indian standards (IS 456-2000)[1], (IS 1893-1, 2016)[2], (IS 875-1, 1987)[3] and (IS 875-2, 1987)[4] as key references when considering factors associated with static and dynamic loads. Latha M.S, Pratibha K(2020)[5] paper help me to understand through there paper that the conventional slab experiences the highest deflection in a regular structure, while in irregular structures, the grid slab demonstrates the greatest deflection. Additionally, in both regular and irregular structures, story displacement is maximized in the grid slab system and minimized in the conventional slab.

1. Introduction: The research project, titled "Investigation and Comparative Analysis of Multi-Storey Building Structures using Conventional Slabs and Grid Slabs in ETABS," aims to explore and contrast the structural behaviour of two distinct slab types—conventional and grid slabs—in the context of multi-storey buildings. Employing the ETABS software for analysis and design, the primary goal is to evaluate the efficiency of these slabs within both symmetric and asymmetric building layouts. The assessment encompasses a thorough examination of floor slab performance under various structural conditions, considering gravitational forces, lateral forces, seismic activity, and wind forces. The design of multi-storey buildings takes into account factors such as dead loads, live loads, wind loads, and seismic forces to understand their impact on structural
