Abstract
Strengthening of masonry walls is a key aspect during building retrofitting operations having conservation goals. "Reinforced repointing technique" involves the application of materials having high tensile strength such as steel bars, steel textile sheets or composites thin pultruded laminae with cracks arrestors function, to reduce the vulnerability of masonry structures against in-plane and out-of-plane actions. In this paper, a three-dimensional numerical model is developed to evaluate the efficiency of reinforcing steel bars facing crack propagation phenomenon under increasing compressive loads.File in questo prodotto:
