ICAR/09 - Structural engineering

The research focuses mainly on topics relating to:

• the computation of the load carrying capacity of reinforced (RC) or prestressed (PC) concrete sections and structures
• the behaviour of slender RC and PC members under instantaneous and long term loads
• the analysis of viscoleastic heterogeneous sections and structures under long-term loads

Some numerical and experimental investigations that fall under the first research theme refer to compact cross sections cast in consecutive stages (e.g. precast beams with a cast in situ slab), as well as beams reinforced, prestressed or externally bonded with either steel, or composite materials, loaded by means of static or oligocyclic loads or high temperature.

The researches on the delayed behaviour of thin walled heterogeneous viscoelastic beam, heterogeneous viscoelastic compact cross sections cast in consecutive stages, timber-concrete composite beams, cable-stayed bridges are examples of the effort spent on the third theme.

To these issues have recently been added:

• the study of wooden beams retrofitted or strengthening both with glued wooden boards and with inserts (Near-Surface Mounted) of composite materials
• problems related to the retrofitting of masonry structures (such as, for example, the verification of the punching of the walls under a tie rod anchor system, determination of the extent and distribution of pressure in the beam-wall contact area, optimal distance between the chains placed under a masonry vault)
