Analysis of location of composites reinforcement of masonry structures with use topological optimization

Abstract Masonry structures, which are subjected to in-plane shearing, should be reinforced. The situation is often appearing in the regions, where masonry buildings are destroyed due to earthquakes. There are many methods of strengthened this kind of structures. One of them is reinforcement by FRP composites, which are linked to the masonry surface. It is not quite simple to select a place, where the composites should be to obtain the most effective work of behaviour. In the paper the topological optimization is used to meet this goal.
