Experimental Study On Composite Encased Steel Beam With Different Guage And Sections

Abstract

A composite encased steel beam is a structural element where a steel section is embedded within concrete. This integration enhances the strength, stiffness, and durability of the beam, making it an efficient choice for modern construction projects. The concrete provides compressive strength, while the steel contributes tensile strength, ensuring optimal structural performance.

The primary objective of this study is to evaluate the mechanical behavior of composite encased steel beams with different gauges and sections under various loading conditions. The experimental investigation involves material selection, mix design, beam casting, and testing of the specimens for load-bearing capacity, deflection, and failure modes. A comparative analysis is conducted between composite encased steel beams and conventional reinforced concrete beams to assess their performance advantages.

Through extensive research and experimental trials, significant improvements in strength, ductility, and deformation resistance have been observed in composite encased steel beams. The results demonstrate that increasing the steel gauge enhances the beam’s ability to resist bending and shear forces. Additionally, the composite action between steel and concrete contributes to better load distribution and crack resistance, making it a viable alternative to traditional construction methods.

This study provides insights into optimizing the design of composite encased steel beams for future applications in high-rise buildings, bridges, and infrastructure projects. The findings serve as a foundation for further research on dynamic loading conditions, durability, and cost-effectiveness.
