| Abstract: | The strengthening technique by use of the external prestressing method has been widely used in reinforced concrete(RC) beams.In this paper,experimental research on the two-way slabs strengthened with the external prestressing method is carried out.The bearing capacity and working performance of the strengthened slabs are analyzed,and the concentrated-laying way is proved to be the most useful one for external prestressing tendons. |

| Keywords: | strengthening external prestressing reinforced concrete two-way slab ultimate load |
