Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Civil Engineering Summary: In this research different methods of strengthening of flat slabs with edge openings are studied theoretically and experimentally. The experimental programconsistsof six square slabs with dimensions of (110*110*10) cm with cut-out edge opening of 30cm*30cm. Two slabs are considered as reference slabs with and without opening. The other four slabs were strengthened using various methods including additionalsteel bars, Carbon Fiber Reinforced Polymer (CFRP) strips, steel plates and bolts andnear surface mounted Engineered Cementations Composite (ECC) steel mesh 10cm*10cm on the tensile face only. In addition, a numerical Finite element model is used to correlate and explore various conditions for strengthening techniques.The results showed that, the ultimate load carrying capacity increasedfor all the repaired slabs. Also, strengthening by steel bars was the most effective method of repair.
