| Abstract: | This paper presents the experimental research on reinforced concrete slabs with complex boundary conditions, and the crack, yield and ultimate loads on slabs are studied. An analysis by nonlinear finite element program of reinforced concrete slabs has been made for the whole history of loading and effect of different supporting conditions and placing of steels on the yield line and the bearing capacity have mainly been investigated, as well as the function of the strengthening strip, deformation of slabs etc. |

| Keywords: | reinforced concrete slabs nonlinear finite element point support yield line strengthening strip |
