Machine learning framework for predicting the shear capacity of demountable bolted connectors in composite beams [PDF]
Scientific ReportsSteel–concrete composite beams are increasingly adopted in modern construction owing to their high strength, stiffness, and efficiency. Conventional welded shear connectors, while effective, hinder disassembly and recycling, limiting their alignment with

Experimental and numerical study of tubular steel columns with/without demountable bolted shear connectors embedded in the concrete [PDF]
Scientific ReportsThree push-out specimens were experimentally tested to investigate the behavior of tubular steel columns (TSC) with and without bolted shear connectors embedded in normal concrete (NC). Each specimen consisted of a tubular steel column (TSC) encased in a

Experimental study on demountable shear connectors in composite slabs with profiled decking [PDF]
Journal of Constructional Steel Research, 2016 Abstract This paper presents an experimental study on shear strength, stiffness and ductility of demountable shear connectors in metal decking composite slabs through push-off tests. Twelve full-scale push-off tests were carried out using different concrete strength, number of connectors and different connector diameter.

Engineering Structures, 2019 This paper presents the results of an experimental programme to investigate the performance of a new composite shear connector that can be used to build deconstructable composite floors. A total of 21 push-out tests were conducted to quantify the effects of different design parameters, including different nominal temperature levels (20 °C, 100 °C, 300 °

Push‐out tests of demountable shear connectors for sustainable composite structures
Steel ConstructionAbstractThe demountable shear connector is the most important component of sustainable composite structures, as it allows the elements to be reused. The ongoing research and development project – in the cooperation of the Budapest University of Technology and Economics and KÉSZ Group, bim.GROUP Ltd., Hungary – aims to design a new demountable steel ...
