Investigation of Composite Structures in Comparison to RCC Structures using ETABS
Faizan Rafiq Wani, ER. Ajay Vikram
High rise structures are becoming very common everywhere due to scarcity of land and increasing population. Though we have the RCC structure system as high-rise buildings, in RCC buildings due to the bulky size of the components of the structure, self-weight will be more due to the heavy density of materials. By observing the difficulties and challenges in the field of high-rise structures engineers are using an efficient structural system that is Steel Concrete Composite Structure. Composite structure consists of a composite deck slab, composite beam and composite column. Composite Structure comprises Concrete which is good in compression and structural steel which good in tension and composition of these materials makes structure better in ductility which comparatively on higher side than RCC structure. Here G+7 high rise structure is considered for analysis by ETABS software. This paper involves Analysis of Commercial building by Equivalent static method on Composite structure and RCC structure with same plan of building and same design data. The structure is in earthquake zone III and wind speed 44m/s. Analytical comparisons of both Composite and RCC frames based on structural parameters are made with the help of graphs and tables. By comparing the results, we found that Steel-Concrete Composite Structures are more desirable than RCC structures. Composite structures, comprising reinforced concrete (RC) elements and steel components, have gained significant attention in the construction industry due to their superior strength, durability, and efficiency. This research paper aims to investigate and compare the behavior of composite structures with traditional reinforced concrete structures (RCC) using the ETABS software. The study includes a comprehensive analysis of various structural parameters such as structural performance, load-carrying capacity, deflection behavior, and cost-effectiveness. The findings of this research will provide valuable insights into the advantages and limitations of composite structures, enabling engineers and designers to make informed decisions during the design and construction process.
