• Resumen

  • Residential construction traditionally relies on solid structures, leading to inflexible buildings that often require significant modifications to accommodate changes. This inflexibility frequently leads to premature demolition of buildings. The short lifespan of residential buildings calls for rethinking this practice, so future constructions should embrace more adaptable and open structures. This paper investigates an innovative hybrid clay-filled steel construction that offers greater adaptability, by utilizing smaller cross-sections and folded steel sheets instead of cold-rolled steel profiles, while using Cleancrete™, a clay-based material that provides necessary fire protection for the steel components. A series of full-scale four-point bending tests were conducted to assess the load-bearing capacity of the proposed composite beams and the reinforcing effects of Cleancrete. The data from the experimental studies demonstrates that the new system meets both ultimate and serviceability limit states, highlighting its potential for direct implementation in sustainable, flexible residential construction.
