| Summary: | 碩士 === 國立成功大學 === 土木工程學系碩博士班 === 96 === This paper use ABAQUS software to analyze different shapes of concrete columns under axially loading strengthened by fiber reinforced composite materials and the relationship of axil stress and axial strain. Mainly propose more rational nonlinear analyses by considering the true material behavior, using ABAQUS to calculate this nonlinear numerical value. Comparing numerical results with experiment data , and checking accuracy of numerical models.
This paper compares three shapes including circular, square, and rectangular, individually nineteen, six, two specimens of different strength of concrete, and properties of composite materials. The result shows that, after adjusting the value of lateral pressure, the prediction can be accurate in concrete strengthed by fiber reinforced composite materials. And the trends of its stress-strain curve are all quite identical with the experimental data. The way to analyze concrete columns under axially loading in proving the model of this paper is rational and accurate.
