文摘

Proposes new composite beam with high-level sustainability attributes. First use of a composite beam with a precast geopolymer slab. FE modelling is developed and invoked to assess the structural feasibility of the beam. Deconstructability of the novel beam is achieved using high-strength friction-grip bolted shear connectors. Tests and FE model confirm highly ductile and more favourable strength than conventional composite beams.
