Strengthening of Full Scale RC One - Way Slab With Cutouts

In this study the nonlinear finite element method used to analysis full - scale reinforced concrete slab with opening strengthening with overlay concrete or CFRP sheets. The FE model proposal in this study are simulate by using results of experimental work f rom previous study. The strengthening models proposal in this study by using overlay concrete increase load carrying capacity of slab by amount vary from (5 to 30) % of slab strength, when strengthening by using CFRP sheet increase load carrying capacity f rom (10 to 65)% of slab strength.
