Abstract: Unreinforced masonry (URM) structures have shown their vulnerability to major events like as earthquakes, severe wind, blast, and impact. The present work started from experimental programs available in scientific literature ...

Abstract: Previous experimental studies, conducted by some of the authors, on in-plane response of tuff masonry walls strengthened with an innovative cementitious matrix composite grid (CMG) system confirmed that the CMG system could ...

Abstract: Internal transverse steel reinforcements (e.g., stirrups) are the main internal devices that prevent the longitudinal steel bar buckling, but in many existing reinforced concrete (RC) structures the amount and the spacing ...

Abstract: Innovative materials and technologies have been developed to limit the effects of earthquakes on structures, and the use of composite materials has been shown to be effective in existing buildings. In view of this background, ...

Abstract: The external confinement of RC columns by means of externally bonded fiber-reinforced polymer (FRP) laminates is a well established technique for strengthening and retrofitting purposes. This paper presents a pilot research ...

Abstract: Reinforced concrete (RC) hollow piers in bridges withstand high moment and shear demands ensured with reduced mass and lower stress on foundations compared with solid piers. Failure of hollow columns is typically affected ...

Abstract: Nowadays retrofitting and strengthening of masonry buildings are important challenges for structural engineering to ensure the structural safety under seismic or exceptional loads. This paper aims to clarify the effects ...
