Effect of Near-Surface Mounted Bars on the Structural Behavior of One-Way Rc Slab

Abstract

The present research paper deals with the finite element modelling of continuous one-way reinforced concrete (RC) slabs strengthened by near surface mounted (NSM) bars under static loads. Seven specimens that consisted of one reference slab without strengthening and six strengthened slabs were used, with 2400 mm total length, 500 mm width and 100 mm thickness.The average compressive concrete strength at 28 days' age was about 31MPa was used. Slabs were simulated with finite element computer program. The results of the control and strengthened slabs were compared with the experimental results. It is observed that the results of the strengthened slabs are in close agreement with the experimental results with a maximum difference in the ultimate load of about 6.64%.
