Abstract
Steel-Encased Timber Composite (SETC) beams offer a sustainable and high-performance alternative for structural applications by combining the strength of cold-formed steel (CFS) with the resilience and environmental benefits of timber. This study investigates the influence of key design parameters, including CFS thickness, profile variations, timber grade, and screw spacing, on the structural behavior of SETC beams. Experimental analyses was conducted to evaluate load-bearing capacity, ductility, and failure mechanisms. Results indicate that profile modifications, such as the inclusion of lips and plate reinforcements, significantly enhance structural performance. Additionally, the study highlights the importance of optimized screw spacing and timber grade selection in achieving an effective balance between strength and ductility. The findings provide valuable insights for the optimized design of SETC beams, contributing to the development of efficient, durable, and sustainable composite structural systems.
