Tóm tắt
This study presents a numerical study on the structural behavior of reinforced concrete (RC) beams strengthened with Engineered cementitious composites (ECC) layer and Carbon Fiber Reinforced Polymer (CFRP) sheets. The numerical model was developed using ABAQUS/CAE three-dimensional finite element (FE) model package, in which material nonlinearities were considered. By comparing with experimental results reported in the literature, it was shown that the numerical modelling findings agreed well with test data not only in terms of failure mode but also flexural strength capacity. The average deviation between the experimental and modelling results in terms of flexural strength of strengthened RC beams is only 4.4%. This demonstrates that the developed FE model can be a powerful tool in the assessment of the strengthening efficiency of RC beams strengthened with ECC layer and CFRP sheets.
