RESUMO:

This paper presents an investigation on the magnitude of the internal stresses at the concrete and at the steel on concrete slabs with overlay increase subjected to static flexural loading.

Using ANSYS, stresses were analyzed with finite-element modeling (FEM), of three configurations of reinforced concrete slab panels measuring 1,70x0,60 cm: an intact slab with 10-cm-thick, two repaired slabs with 10-cm-thick strengthened 5-cm-thick bonded overlay and a two 15-cm reference slab. The research project included experimental testing to measure the evolution of the structural capacity and the cracking behavior of five slabs. Results of the analyses are compared with experimental data for the purpose of verification. The analyses showed a good relation between the experimental results and the results obtained in the computational model. Thus, the proposed model could simulate the behavior of strengthened slabs, even after cracking.
