AISC Research: Design for Deconstruction: Sustainable Composite Floor Systems with Deconstructable Clamping Connectors [G3]

A sustainable composite steel-concrete floor system for building structures is proposed to enable disassembly and reuse of the structural components, thereby reducing the environmental impacts associated with material extraction, production, fabrication, and waste disposal. In this system, deconstructable clamping connectors are utilized to attach precast concrete planks to steel beams. The load-slip behavior of the clamping connectors was studied in pushout tests. The results show that the clamping connectors have excellent slip capacity as well as shear strength comparable to that of traditional shear studs. Four full-scale beam tests were then conducted to investigate the flexural behavior of the deconstructable composite beams under gravity loading. The flexural strengths of the composite beam test specimens closely match the strengths predicted by AISC design provisions. All the beams behaved in a ductile manner.
