Effect of rebars length above inner supports of continuous RC slabs

The paper first presents the results of experimental tests of limit strength capacity of a continuous reinforced concrete slab with two spans. The slab was loaded with point load in the middle of each span. The effect of the tensile rebars length above the inner support on the limit strength capacity of the slab was analyzed. Already developed numerical model by the authors for the analysis of reinforced and prestressed concrete slabs and shells, was additionally tested on the obtained experimental test results. The limit strength capacity of a one-way continuous reinforced concrete slab with two spans and different tensile reinforcement arrangements above the middle support, loaded by a uniformly distributed load, were analyzed by the model. The length of tensile reinforcement above the inner supports of one-way continuous slabs affects the limit strength capacity and deflection of slabs.
