About

The project is dealing with the shear transfer in heavy steel-concrete composite columns with multiple encased steel profiles. In the conducted research, a focus was placed on two aspects of shear transfer: (1 local shear transfer at the steel-concrete interface and (2 global shear transfer between the embedded steel profiles. With reference to the current practice, gaps in the knowledge and in the available solutions have been identified. A complex interaction between the materials and lack of knowledge regarding composite behaviour in columns with multiple encased steel profiles opens opportunities to develop novel systems and design methods. The described objectives are investigated experimentally and by the FE numerical simulations. As an outcome, an analytical model for the resistance of the developed novel shear connectors and innovative mechanical engineering model for the description of the structural behaviour, as well as effective stiffness, of a composite member with more than one embedded steel profile are given.
