Sustainable Hybrid Steel‐Timber Beams with Demountable Shear Connectors: Ambient and Fire Tests
Abstract
Abstract Global warming, driven by excessive CO 2 emissions to the atmosphere, represents one of the major current threats. The construction industry, responsible for a significant environmental impact, is undergoing a transformation towards more sustainable practices, promoting the transition from a linear waste management model to a circular approach, where materials can be recycled and/or reused. In this context, demountable shear connectors play a key role by enabling the recovery of structural components and extending their service life. This paper presents the results of an experimental study on hybrid steel‐timber beams with demountable shear connectors, an innovative system that incorporates sustainable materials (i.e. timber) as a partial replacement for those with a high carbon footprint (i.e. concrete). The experimental campaign comprised four hybrid steel‐timber beam tests: two at room temperature and two under fire conditions, considering an innovative fire protection system. The findings of this investigation ensure the structural efficiency of hybrid steel‐timber beams with demountable shear connectors under both ambient and fire conditions, while reinforcing their alignment with the principles of the circular economy and their contribution to reducing the carbon footprint in the construction sector.
