About Dr Gianluca Ranzi
Gianluca decided to move into research to gain a deeper insight into the behaviour and design of structural systems. With time he also became fascinated by the properties of light metals and decided to focus his research on the characterisation of their mechanical properties.
Gianluca's work aims to understand the service and ultimate behaviour of composite steel-concrete structures and to characterize structural systems formed by monolithic and multilayered materials.
Gianluca has been active in research in the area of composite steel-concrete structures and of characterisation of light metals. In the last few years he has developed rigorous methods of analysis for the modelling of composite steel-concrete members with partial interaction. He has developed novel formulations for two- and multi-layered beams with both longitudinal and transverse partial interaction as well as demonstrated analytically the origins of locking phenomena in finite element formulations for composite applications. Recent work has focused at developing a new analytical and numerical model to account for shearing deformations in composite members which has identified their influence in well predicting the deformation state of realistic design applications. He has also devoted particular attention to the modeling of structural systems affected by the long-term behaviour of the concrete and by thermal effects as would occur in a fire situation. In both instances he has developed new analytical and numerical models. In the area of light metals he has been focussing his attention on the implementation of inverse analysis techniques for the characterisation of the material properties of monolithic and multi-layered systems.
