These three specimens underwent compression test and the results are tabulated and compared. A comparative analysis of the local and post-local buckling behavior of different composite sections has been studied and the column sections have been designed according to Eurocode 4 (ENV 1994) to determine the plastic resistance of the section. As a result, material testing for cement, fine aggregate, and coarse aggregate was completed, as well as a concrete mix design. The raw materials' natural properties are assessed. Three specimens were chosen for this study: one was a composite column, the other two were ordinary RC columns and structural steel columns. The steel-concrete composite system combines the formability and rigidity of reinforced concrete with the ductility and strength of structural steel to meet the demand for earthquake-resistant constructions.
The main objective of this study is to analyze the behavior of steel-encased concrete composite columns as experimentally under axial compression and the mode of failure under ultimate failure and yield point.
This research comments on the behavior of composite columns. Columns as a structural element play a vital role in structural frame. This stands tall than the ordinary and conventional type of constructions. Composite sections are found to be a novel technique in modern day scenario of construction.
