| الوصف: | Publisher's version (útgefin grein) This article investigates the material behavior within multiple-component systems. Specifically, a structural concrete element strengthened to flexure with externally-bonded fiber-reinforced polymer (FRP) material is considered. Enhancements of mechanical performances of the composite structural element resulting from synergies in the framework of the multiple-component system are studied. The research work comprises the determination of the constitutive relations for the materials considered separately as well as the investigation of materials' response within a complex system such as the composite structural element. The definition of the material models involves a calibration of the model constants based on characterization tests. The constitutive relations are integrated into the finite element model to study the material behavior within the multiple-component system. Results obtained by finite element analysis are compared with experimental results from the literature. The finite element analysis provides valuable information about the evolution of some internal variables, such as mechanical damage accumulation. The material synergies find expression in the load-carrying capacity enhancement and the delay in the damage accumulation in concrete. The experimental program discussed in the present study was carried out at the University of Reims Champagne-France, within the Ph.D. research work of the author, supported by the French Government. The early stages of the numerical investigation were carried out at the University of Reims Champagne and the University of Lille, LML-France. All support to the preparation and the realization of the experimental program, as well as the enlightening discussions, are gratefully acknowledged. "Peer Reviewed" |
