Seismic performance of a masonry house prototype retrofitted using frp strip: a numerical study

Ahmad Basshofi Habieb, Marco Valente, Gabriele Milani

Abstract


This study presents a series of finite element analyses on the prototype of masonry house retrofitted using FRP strips. The model of the masonry house refers to the prototype scaled to 1:3 tested in an experimental campaign. The non-linear behavior of masonry is modeled through the Concrete Damage Plasticity (CDP) model, while the FRP and adhesive are modeled as two separated isotropic solid materials with elastic-plastic behavior. A good agreement between experimental and numerical result is obtained, indicating the increase of bearing capacity of the reinforced masonry prototype.
