There are number of structures that either require local reinforcement or even have been locally reinforced during their construction. For example, a number of historic buildings in Prague, the capital of the Czech Republic, are built up with different local reinforcement, such as goat hair, fibers of different kinds (steel, plastic, glass, etc.). The historic buildings are exposed to current climate conditions and heavy traffic pollution, which are both very damaging to the quality of the original mortars. This is why the necessity of refurbishment of the old building is obvious. The fibers locally reinforce concrete, particularly in exacting conditions, such as shotcrete in tunnel construction, foundation engineering, etc. The aim of this paper is to compare experimental data with results from a numerical model to get information on the mechanical behavior of the locally reinforced material for further theoretical studies.
