This study verified the effect of Metal-Grid with PCM as thickness reinforcement to the load carrying capacity and stiffening effect of RC beam deflected to 1/400 of the beam span. Results shows that the load-carrying capacity of reinforced crack-repaired RC beam using Metal-Grid expanded type and square cut type was increased 1.61 and 1.59 times respectively as compared to that of the un-reinforced RC beam. Furthermore, the load carrying capacity of both Metal-Grid reinforced damaged RC beam with thickness increased by PCM was equivalent to the load carrying capacity of the non-damaged reinforced RC beam. Therefore based on the result on the damaged RC beam, we can conclude that Metal-Grid, both expanded and square-cut type, and PCM as thickness reinforcement are effective reinforcement methods for damaged concrete.
