Research Topics

  • Performance-based design of steel-concrete composite bridges

    This research activity regards the applicability of a new design philosophy to small-medium span steel-concrete composite: the Performance-based design approach. In this respect a European project proposed by a wide international team and coordinated by writer, has been funded in 2012 by the Research funds on Steel and Coal (RFCS) of the European Commission (SEQBRI Project)

  • Assessment of the seismic response of existing bridges and applicability of seismic isolation systems

    This activity is subdivided in several sub-themes:

    1) definition of protocols for in-situ investigation of the mechanical characteristics of concrete
    2) methods for the seismic assessment of structures,
    3) design and execution of experimental tests (cyclic and pseudodynamic) on old R.C. bridges with portal frame piers,
    4) definition of accurate models to account for degradation phenomena (bond-slip, buckling of steel bars, strain-penetration, flexural-shear interaction,
    5) evaluation of the seismic risk of existing bridges under the action of mainshocks and aftershocks,
    6) applicability of seismic isolation systems. On this subject the several research projects has been funded by National and International Research Institutions (Reluis, Series TA – RETRO).

  • Seismic risk of major-hazard industrial plants and applicability of innovative protection systems

    Base isolation and energy dissipation

    The main goal of this activity is the study of the seismic behaviour of industrial components installed in chemical and petrochemical plants, particularly vulnerable to earthquakes. A second goal of this research is the study of the applicability of passive control systems for the seismic protection of industrial structures. From 2004 to now several research projects have been funded providing important contributions on the theme of seismic response of tanks and piping systems (ISPESL grant, RELUIS 2). In addition several workshops and courses have been held.

  • Reduction of Seismic vulnerability of HV equipment and substations

    The activity regards the evaluation of the seismic behaviour of high-voltage electrical equipment and design of a passive control system for its seismic protection. In particular, Experimental activity on electrical equipment, Fragility analysis of electrical apparatuses, evaluation of the seismic vulnerability of electric substations, proposal of a new base isolation system based on steel cable dampers. This activities have been carried out within several research projects (VIA project funded by INVG and a grant provided by TERNA)
