| dc.description.abstract | 本研究為探討不同節型鋼筋於混凝土中之握裹行為。共製作30 組梁端鋼筋錨定試體，採用梁端偏心拉拔之試驗形式，模擬具有適當橫向圍束竹節與光面鋼筋之受撓構件中鋼筋的直線握裹行為，探討鋼筋在臨界斷面處發展斷筋伸展長度下，其握裹應力與不同鋼筋節型間的關係。過去曾對於竹節鋼筋與混凝土之握裹性能及螺紋節鋼筋與混凝土之握裹性能進行研究，針對不同鋼筋節形與混凝土握裹行為之相關研究較少。本研究考慮在不同主筋節形、主筋脊位置、箍筋強度、混凝土強度、包含混凝土保護層及橫向鋼筋圍束的劈裂指數（超過上限值2.5）及鋼筋表面之幾何形狀指標Rr（節高與節距之比值）下，鋼筋與混凝土間的握裹行為。 | zh_TW |
| dc.description.abstract | The purpose of this study is to investigate the gripping behavior of different nodal types of steel bars in concrete. A total of 30 sets of beam-end reinforcement anchoring specimens were made, and the beam-end eccentric pulling test was used to simulate the straight-line wrapping behavior of steel bars in a flexural member with appropriate transverse confinement bamboo joints and smooth steel bars. The relationship between the wrapping stress and the different types of steel bars under the extension length of the broken bar developed at the surface. In the past, there have been studies on the gripping properties of slub-jointed steel bars and concrete and the gripping properties of threaded-section steel bars and concrete, but there are few studies related to different shapes of steel bars and the gripping behavior of concrete. In this study, different main bar nodal shapes, main bar ridge positions, stirrup strength, concrete strength, splitting index (over the upper limit of 2.5) including concrete cover and transverse reinforcement bars, and the geometric shape index Rr of the steel bar surface were considered. The ratio of height to pitch), the grip behavior between steel and concrete. | en_US |
