[en] In order to improve sustainability of composite structures and promote the principles of circular
economy in construction industry, novel demountable shear connector based on the frictional
behavior was developed within the framework of Work package 2 of parent project ECON4SD
(Eco Construction for Sustainable Development) at the University of Luxembourg.
The demountable composite floor system is composed out of modular concrete one-way solid
slabs with equidistantly embedded Halfen HTA-CE rail channels, double symmetric steel I section
and demountable connector device assembly based on HV high strength structural bolts for
preloading that provides the demountable shear connection.
In this paper trilinear behavior model is proposed for the force-slip behavior of aforementioned
connector device complying to the results of the push test experimental campaign and the results
of FEA simulations. Afterwards, parametric study is performed on the range of simply supported
composite beams in propped and unpropped condition under uniformly distributed load applying
the aforementioned shear connection validating the predictability of the composite beam bending
behavior in accordance with the rules of EN 1994-1-1.
