| Summary: | 碩士 === 國立成功大學 === 土木工程學系專班 === 94 === This paper use ABAQUS software to analyze uneasily compressive loading and relationship of axial loading and axial strain of the concrete confined by fiber reinforced polymer (FRP) composite jackets. Mainly propose more rational nonlinearity and analyze the way by considering the true material behavior, make use ABAQUS to carry out this non-linear number value to calculate. Via verifying with the existing experiment materials, exactness by way of confirming and analyzing.
And the relation that the stress-strain of discussing the different concrete , width-to-thickness ratio(D/t), lateral pressure (fl)and parameter of concrete softening(k3) of concrete confined by FRP.
This paper compares nine groups’ specimens of different strength of concrete, thickness of composite. The result shows, after adjusting lateral pressure (fl) value and parameter of concrete softening, the prediction that can be accurate encloses the axial compression strength of a bunch of concrete. And the trends of its stress-strain curve are all quite identical with the experimental data, the analysis way to prove this model of this paper is rational and accurate.
