Optimization of a composite (steel-concrete) floor system for fast execution and easy demolition. Computational homogenization simulation on steel reinforced resin used in the injected bolted connections. Elastic behaviour of a tapered steel-concrete composite beam optimized for reuse. The void between the bolt and bolt hole in the top flange is filled using epoxy resin, to achieve composite action under live loading. Given the needs for larger execution tolerances of steel and concrete products, oversize holes are used in the beam flange to allow for rapid execution and easy demounting of the composite floor system. Within the project an innovative demountable shear connector has been developed, consisting of an external (injection) bolt which connects to a coupler and bolt embedded in the concrete deck. An example of a demountable shear connectors are embedded bolted shear connectors, which are used connect the prefabricate deck and the top flange whilst allowing for demountability. An important step is to develop demountable shear connectors, since structures with welded headed studs cannot be demounted without damaging the concrete deck.
A key focus of the project is to develop and test efficient demountable composite construction systems that are key to retaining and growing market share for steel construction. The main application of the project is in multi-storey steel framed buildings, which often use composite construction for structural efficiency, speed of construction, and cost efficiency.
The REDUCE-project addresses the increasingly important requirements for design to facilitate reuse of structures, which is an important part of the circular economy initiative that underpins the sustainability and environmental impact of the built environment within the European Union.
