ABSTRACT
In the paper one summarizes a recent model for designing the reinforcement optimal distribution in the case of some planar elements, e.g. fiber-reinforced-polymers strips glued onto the surface of the masonry walls or internal tensile bars inserted in the concrete beams. The body material is considered continuous, homogeneous, isotropic, linearly elastic and resistant compression, so that a no-tension model where the tensile resistance is considered null is adopted. The reinforcement is considered to have an unlimited strength and is adopted exclusively where the fractures occur. In this way the procedure evaluates automatically the quantity of reinforcement that is necessary and the areas where it is needed. As regards to the adopted procedure one refers to the fundamentals of limit analysis combined with the topological optimization and some examples of solution are shown.
