STRUCTURAL ENGINEERING

The main research topics of the group can be summarized as follows:
a)    Development of non-linear constitutive models for ordinary, fiber reinforced and prestressed concrete members, under static, cyclic loads and in presence of fire
b)    Non-Linear Finite Element Analyses (NLFEA) of reinforced concrete structures (e.g. slabs, ties, beams) and development of guidelines for NLFEA of existing bridges
c)    Experimental and numerical analyses of precast pre-stressed R/C elements: 
-    thin-wall roof elements
-    hollow core slabs and floors, also with openings
-    precast frames and connections between precast members
d)    Experimental and numerical evaluation of the mechanical effects of steel fibers addition into concrete
e)    NLFEA of concrete tunnel linings during construction stages, in service conditions and under fire load
f)    Vulnerability assessment of existing structures and analysis of strengthening techniques:
-    FEA of ancient masonry structures, such as towers and vaults;
-    Behaviour of structures strengthened by FRP and FRCM (bond, cracking);
-    Seismic behaviour of castles, ancient theatres, historical buildings (seismic assessment, and dynamic identification)
g)    Seismic risk assessment of existing RC structures and infrastructures (fragility curves) and of RC structures for nuclear power plants by advanced numerical methodologies
h)    Development of construction eco-materials through physical-mechanical characterization:
-    Circular cementitious materials containing waste (biochar from pyro/gasification of wooden biomass, recycled plastics; vitrified municipal solid waste incineration ash), in collaboration with D. Milanese and C. Sciancalepore (ING/IND22, DIA), and A. Malcevschi (SCVSA), including durability and corrosion resistance measure in steel reinforced elements;
-    New alkali-activated binders and mortars, in collaboration with C. Graiff and L. Bergamonti (SCVSA)
-    Optimization of aerated autoclaved concrete masonry and its components to improve their energy efficiency and seismic performance
i)    Material deterioration and corrosion processes in RC and PC members: inspection methodologies, experimental test and implementation of models for the capacity assessment and residual life estimation
j)    Robustness and resilience performances of cast in situ and precast concrete structures: analytical approaches, numerical methods, and validation of pre-normative rules for the new generation of Eurocodes
