Currently as an expert, he holds the following institutional positions:
• Ministry of Infrastructure and Transport - Expert Member of the C.T.A. of the Interregional Provveditorato per le Opere Pubbliche Sicilia e Calabria;
• C.S.LL.PP.– Member of the Commission for the management and monitoring of the experimentation provided for in paragraph 4 of Article 49 of Legislative Decree no. 76 of 16/07/2020
During all these years, he developed principally his activity of research about:
• the behavior of non-linearly restrained slender bridge piers. A numerical method was developed to perform a geometrically and mechanically non linear analysis of the piers. It also takes into account the evolution up to failure of the behavior of the restraints. By means of computation on a large number of different restraint conditions on a real bridge, it is shown to what extent the restrain effects exerted by the bridge deck may affect the safety factor on the action side of the piers. Elastic-rigid restraints and sliding-rigid restraints are considered; both of them are able to stop after a predetermined displacement value, becoming infinitely rigid beyond this value;
• the interaction of axial force, bending moment, and shear force (N, M, V) in reinforced concrete. A new model able to compare in a reliable way with the experimental evidence has been proposed. The work generalizes the variable-depth stress-field approach, allowing to consider the effect of longitudinal and transversal reinforcement in the web and to analyze Rectangular, Box and I-shaped cross-sections subjected to M, N, V by interaction domains, which provide a powerful tool for optimizing the disposition of reinforcements and for maximizing the cross-section strength. The obtained N-M-V failure surfaces are in good agreement with the experimental evidences of tests found in literature;
• the interaction of bending moment, and shear force (M, V) in prestressed concrete. The analytical model is the generalization of the previously proposed model for the N-M-V interaction, based on the stress-fields approach, which now includes the effect of prestressing tendons, thus providing a unified approach for reinforced concrete and prestressed concrete elements. The reliability of the model has been validated by comparing its numerical results both to experimental results already analyzed for reinforced concrete beams and to the strength values obtained by means of failure tests performed on thin-webbed prestressed concrete beams, reported in literature;
• the study on fatigue stresses in end zones of bridge stays induced by wind vibrations. The effects induced by the geometric non-linearity of the structure have been taken in account, determining the equations of motion through an original continuous approach by using the Hamilton's principle. The problem has been carried out in the time domain and the cable has been idealized as a bending stiffened cable in large displacements field, reducing the dynamic problem and using the Galerkin approach. Results, obtained for cable stays constituted by material usually employees, have shown, therefore, that a complete analysis, taking into account the effects of structural non-linearity of the cable, allows to get more precise and less onerous results of the fatigue damages, in comparison to those that come out by a normal linear analysis in the frequency domain;
• The evaluation of the safety level in concrete structures in serviceability and for durability. In this first work a probabilistic analysis and a fuzzy-probabilistic analysis of bridge prestressed beam is performed in order to evaluate its behavior in serviceability condition, with particular attention to the crack formation limit state. In particular, shrinkage and creep parameters are considered as stochastic variables, adopting a deterministic value for relaxation, due to the severe quality control applied in production of prestressed steel. The comparison of two approaches has put in evidence the peculiarity of fuzzy-probabilistic method, particularly useful when sensitivity analysis should be performed;
Now his interests in research include principally:
• reliability and safety for reinforced and prestressed concrete structures and bridges;
• shear in reinforced concrete members, stress fields and interaction problems related to design procedures;
• bridge design: dynamic behaviour of cable structures subject to wind loads and fatigue problems and optimization and reliability of assembly stages during construction;
• seismic design of reinforced concrete structures provided with protection devices.
