碩士 === 國立臺灣大學 === 土木工程學研究所 === 87 === The study of the research is to understand the behavior of the hollow circular RC bridge pier under the axial compression test. We make small- scalemodels with different confinment of tie steel and get the stress-strain relation of the confined concrete and non-confined concrete. The result of the test show that the main steel and tie steel play an important role in the influence of improvement of the strength and ductility of the column concrete.In the same confined situation,the strength and ductility of solid column are better than hollow one.According to the hollow columns,the strength and ductility of the column with the local-closed tie steel are better than one with single tie steel.
