The paper presents two different modeling strategies for the study of the debonding of anchored Fiber Reinforced Polymers (FRP) externally applied to curved masonry substrates. The first one is based on a fast and computationally effective simple 1D-schematization of specimens based on the use of linear and nonlinear spring elements schematizing the support, the FRP strengthening and the masonry/FRP interface. The second one consists of a tri-dimensional micro-modelling FE approach comprising a damaging behavior of the constituent materials and elastic zero-thickness cohesive masonry-to-FRP interfaces. Both the approaches are presented in detail in the paper and they are validated by considering experimental tests performed by the authors.

Abstract
The paper presents two different modeling strategies for the study of the debonding of anchored Fiber Reinforced Polymers (FRP) externally applied to curved masonry substrates. The first one is based on a fast and computationally effective simple 1D-schematization of specimens based on the use of linear and nonlinear spring elements schematizing the support, the FRP strengthening and the masonry/FRP interface. The second one consists of a tri-dimensional micro-modelling FE approach comprising a damaging behavior of the constituent materials and elastic zero-thickness cohesive masonry-to-FRP interfaces. Both the approaches are presented in detail in the paper and they are validated by considering experimental tests performed by the authors.File | Dimensione | Formato | |
