Composite Columns in Building Structure-A Analytical Study

Abstract

Present day construction is greatly influenced by steel-concrete column composites. Steel-concrete composite gained extensive attention around the globe, which made steel-concrete composite utilization in construction more attractive than conventional reinforced cement concrete design. Different architectural culture has introduced inexhaustible diversification of different columns. One of the most widely used is concrete-encased columns. These columns are those in which steel is encased in reinforced concrete. Combining these two materials leads to less crosssectional area, high rigidity, and improved lateral resistance. However, some construction difficulties are evident. A comprehensive overview of the state of the art of evolution of composite columns in building structures based on experimental numerical and analytical studies is emphasized in the paper. Moreover, replacing concrete with various materials such as cement aggregates, limestones, fly ash, and industry waste is suggested to deal with the high cost of the construction.
