| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程系 === 99 === The main purpose of this study is to discuss the application and the feasibility of the two-dimensional lattice model, which was built using the finite element analysis software ANSYS, on corroded reinforced concrete beams. In two-dimensional lattice models, besides of three different meshing sizes, structural properties corresponding to corrosion of the tensile reinforcement and stirrup must be specified to do the analysis. Compared with the results obtained from the full-size experiment, the two-dimensional lattice model was proved to be with accuracy on the elastic stiffness and maximum strength of the corroded reinforced concrete beams; however, the model cannot simulate the deformation capacity after the maximum strength very well. According to the discussion of the case study, a key point of the simulation using the proposed model is how to input the location of pitting corrosion and uniform corrosion appropriately in terms of the investigation data.
