Analysis of composite concrete steel column using new steel section

Abstract

Conventional concrete encased steel composite columns are typically constructed by embedded “W” steel section or other sections identified in the American Institute of Steel Construction “AISC”, positioned in the center of the concrete column cross-section or around it. The importance of composite elements is found in their common use in big facilities and construction projects where the need for more elements with high compressive capacity and less cost arises. In this research, structural steel is proposed which applies to columns and can be developed to beams. The model is basically a concrete column with steel reinforcement and the proposed steel section embedded. Cost reduction and strength enlargement are the main goals of this paper. A comparative study was done based on results from analyzing three columns, 6 ft long: Finite element analysis was done using ABAQUS software and theoretical analysis using AISC and Eurocode. In addition to a cost analysis on various steel sections. The cost was calculated based on the column weight, length, and price per pound/foot It was concluded that the proposed steel section is cost-efficient and has comparable compressive strength values to the conventional “W” section.
