Comparison of Conventional RCC Columns, Steel Columns and Composite Columns

Abstract

Worldwide, the steel industry is expanding almost everywhere. Compared to the USA, EU, and other developed nations, India uses less steel in the construction industry. Additionally, India's cities have some of the highest population densities per square kilometre, which limits horizontal construction growth and favours vertical development. Steel structures are more ductility and can undergo more deflections while concrete structures are larger and attracts more seismic weight. Hybrid construction combines the advantageous characteristics of both the concrete and steel materials. With the aid of the ETAB programme, the static analysis and Response spectrum technique required by IS1893:2002 are carried out for three-dimensional models of the RCC column structure, steel column structure, and composite column structure. Comparative study of RCC column structure, steel column structure and composite column structure for G+10 is included. Furthermore, the paper addresses the economic implications of these structural systems. It compares the initial costs. Overall, the comparative analysis aims to provide engineers, architects, and construction professionals with valuable insights into the selection of the most suitable structural system for a given project. It helps in understanding the strengths and weaknesses of RCC column structures, steel structures, and composite structures, enabling informed decision-making based on project requirements, budget constraints, and performance expectations.
