Research on 3D printing applications in steel structures

The focal aim of my Ph.D work is the study of innovative metal-based 3D-printed structures for applications in construction.

In particular, the research has been developed through experimental tests and design considerations on Wire-and-Arc Additively Manufactured (WAAM) stainless steel elements. Experimental tests were carried out to characterize the geometrical irregularities and specific mechanical properties of WAAM-produced specimens, with the aim of providing design values of the key material properties and specific design considerations for the application of WAAM technology in the structural engineering field.

From these results, first optimization studies focused on the optimal topology of planar and shell elements and computational design processes for WAAM-produced diagrid structural members were developed. These explorations are intended as examples of the wide range of possibilities on the application of metal 3D-printing technology to realize new-generation of structures with architecturally appealing forms and shapes.

 

Research on earthquake-resistant design of frame structures

My research background lies in the broad field of Earthquake Engineering, with particular focus on the assessment of the seismic behavior of different structural systems and their response in terms of economic losses, damages and fatalities risks, as well as the behavior of steel bracing systems, masonry infill and sandwich RC walls, the latter ones used as earthquake-resistant structures in developing countries to reduce the seismic risk with economically-feasible solutions.
