| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災研究所 === 99 === Abroad in recent years by the CFRP confinement for concrete reinforcement formed after the law has been a considerable amount of research and results. But still has not been a common failure criterion results. The proposed confinement strength of specimens prediction formula they use a complicated process of regression analysis obtained. So the empirical formula is due to a variety of different material properties around the beam. The limited scope of application within the experimental database. Pending further study and discussion.
This study investigated the use of carbon fiber confinement of concrete columns of different size specimens with square columns and was stuck on the cylindrical specimens in compression tests under strain gauges, reached after the destruction of specimens. To discuss further specimens to the measured axial strain and lateral strain rate and make the composition of. In this experiment： 7 different groups were perfusion cylinder aspect ratio (L / D) of the specimens were1、1.25、1.5、1.75、2、3、4. The square columns are three groups of different aspect ratios perfusion (L / W) of the specimens were1、2、4 .Conservation of 28 days after the compression test to measure the value of the stress and strain.
