Comparative Analysis of Framed Tube Structure Using Concrete Filled Steel Tube (CFST) Column with Conventional System

A framed tube structure is a construction concept commonly used in tall buildings, integrating both architectural and engineering principles. This design incorporates interconnected columns that create a frame encircling the building perimeter. In the framed tube structure, Composite Columns, specifically Concrete Filled Steel Tube (CFST), replace conventional columns. CFST sections are created by filling hollow steel tube sections with concrete. Utilizing this structural system in tall buildings offers various benefits, including enhanced lateral stiffness, reduced material usage, and improved fire resistance. Analysis of CFST column framed tube systems will be carried by the ETABS software for their performance under lateral forces including seismic and wind loads. The study encompasses various parameter such as lateral displacement, story drift, Base Shear, Time Period and base reaction, aiming to provide a comprehensive understanding of CFST column with framed tube structural system.
