When a load is applied to a structure reinforced by composite materials, the mechanical behavior is different from the one without composites. As the technology in which the surface of structure is reinforced by fiber reinforced plastics (FRP) is used widely to prohibit the reduction of strength caused by cracking, it is necessary to establish the method of fracture simulation applicable to the reinforced structure. Therefore, a computer program of fracture simulation for the cement mortar reinforced by CFRP or AFRP has been developed in this paper. In oeder to evaluate the computational results, three point bending tests on mortar beams were carried out. The cement mortar beams whose surface is reinforced by FRP sheet are superior in strength to those of cement mortar only. The computational results have a good agreement with the experimental ones. As a result, it is clear that the developed computer program of fracture simulation is very useful for design of structures with composites.
