This paper presents the main aspects of a comprehensive study of demountable steel-precast concrete connections consisting of a demountable bolt and embedded mechanical coupler with a rebar anchor. The study included experimental and numerical analysis of the connection under pure tension, pure shear, and combined shear and tension loading. The research was conducted at the University of Belgrade, Faculty of Civil Engineering and published in the PhD thesis “Demountable connections between steel and reinforced concrete elements with mechanical couplers under combined shear and tension loads”. The distance between the connector and the concrete edge, connector diameter, and concrete strength were examined as the main parameters affecting the failure modes, load-displacement behaviour and corresponding resistance of the connection. The results presented in this paper should contribute to the better understanding of the connection behaviour and design implications.
