Abstract

This work presents the main results of a numerical analysis of the local effects connected to the application of the bed reinforcement technique in historic masonry walls. In particular, CFRP thin strips and lime-based mortar are considered, as reinforcing and embedding materials. On the basis of experimental results, a detailed micro-model has been developed. Mechanical characterization of the basic materials and of the local behaviour of the mutual interaction among them allowed defining the main parameters and constitutive laws to adopt in the model. The model is able to describe the bond phenomenon at local level up to the ultimate loads, identifying the chemical bond stress peak ad its migration along the anchorage length
