Abstract - This paper delves into the benefits of CFST
alternatives. Composite or hybrid materials have emerged as promising solutions, offering enhanced performance without significant changes to manufacturing or construction methods.
(Concrete Filled Steel Tube) columns and profiled steel deck composite roofs, enhanced with graphene oxide nanotechnology, with a focus on space, cost, and time efficiencies. It conducts a comparative analysis of CFST column performance with graphene oxide against RCC (Reinforced Concrete Cement) columns and compares profiled steel deck slabs with RCC slabs. Through multi-case studies and empirical investigation, the study emphasizes the advantages of composite construction in terms of speed, performance, and value. Cost estimates derived from supplier interviews and real-time market values are analyzed alongside conventional RCC structures using Spreadsheet for cost comparison and ETAB for performance analysis, while Primavera software is used for time analysis. The findings reveal significant reductions in construction timelines and costs attributed to decreased weight and elimination of false works. Specifically, a G+17 commercial building project demonstrates a 30.4% cost reduction and a 19.4% time efficiency improvement with composite construction over traditional RCC. The replacement of RCC columns with CFST columns results in the elimination of three columns, maintaining balanced shear stress and bending moments and leading to a 76% reduction in column area, thus achieving significant spatial savings. Furthermore, the incorporation of graphene oxide into concrete enhances strength, reduces permeability, increases resistance to corrosion and cracking, and accelerates curing. This amalgamation of cost efficiency, improved construction speed, and optimized structural performance underscores the advantages of composite construction for commercial building projects.
Despite their clear benefits, the adoption of steel-concretecomposite structures among Indian consulting engineers has been cautious due to perceived complexities in analysis and design. However, existing literature suggests that welldesigned composite systems can deliver cost-effective, timeefficient, and space-efficient structural solutions, boasting rapid erection, durability, and superior seismic performance. Given the evolving landscape and the absence of updated design codes, there's a pressing need to explore composite analysis and design for multi-story buildings, particularly in the Indian context. Our study focuses on interpreting the advantages of replacing traditional R.C.C structures with Concrete Filled Steel Tube (CFST) columns, steel beams, and profiled steel deck slabs in a G+17 Storey building. We assess structural stability, cost, space, and time efficiency while also exploring the benefits of incorporating Graphene oxide, a nanotech material. Through this research, we aim to provide valuable insights into the advantages of composite construction, particularly CFST columns and profiled steel deck slabs, augmented with graphene oxide, within the Indian construction industry.

1.INTRODUCTION
Spatial Comparison with RCC Column: Conduct a spatial comparison between RCC and CFST columns to determine their relative physical dimensions and spatial efficiency.
Structural engineering practices in India have historically favored masonry construction, but modern trends lean towards R.C.C or Steel framed structures for multi-story buildings. The recent surge in interest towards composite structures, spurred by past building failures during seismic events, underscores the industry's quest for safer
