| Abstract: | This study investigates the two-way reinforced concrete slabs strengthened with externally bonded CFRP sheets, which is subject to uniform load under the simply supported conditions.An analytical study concerning the deflection was conducted,and a stiffness and a deflection expression was put forward.The results show that the value from this simplified calculation formula is in good agreement with the experiment data,and the deflection formula has higher precision. |

| Keywords: | two-way slab CFRP sheets strengthen stiffness deflection |
