A new FEM approach for FRP-strengthened RC frames
Owing special mechanical properties has made Fiber Reinforced Polymer (FRP) as one of the best strengthening materials for Reinforced Concrete (RC) structures. The effect of externally applied FRP sheets on RC elements has been the topic of many experimental investigations. On the other hand, simulating the behavior of RC structures strengthened by means of externally bonded FRP sheets is yet to be scrutinized. In this work, a new Finite Element (FE) procedure for inelastic analysis of RC structures has been enriched to account the presence of externally bonded FRP sheets on RC sections. The proposed FE procedure works in the framework of lumped plasticity. It is able to identify the exact …
Monitoring of stress distribution in damaged small-scale masonry walls by using two innovative sensors
Structural Health Monitoring (SHM) represents a strategic solution for the preservation of cultural heritage buildings. Existing masonry structures often suffer reductions in mechanical performances due to physiological aging of material constituents, external actions, and effect of catastrophic natural events. In many cases, the prompt prediction of damage in masonry elements is difficult and it can cause sudden collapses, compromising the safety of people. The proposed experimental study examines the effectiveness of two low-cost and innovative stress sensors, i.e. piezoelectric and capacitive stress sensors, for SHM of masonry structures. To this scope, the sensors were embedded in the m…
