| dc.description.abstract | 台灣都市人口密集且用地有限，新建物多朝向高層建築發展，相較於傳統鋼筋混凝土，採用新型高強度鋼筋混凝土之建築油然而生。主要關鍵技術為採用高強度螺紋節鋼筋與其適用之螺紋續接套筒。高強度鋼筋係指降伏強度為550 MPa及690 MPa應力之SD550W以及SD690。雖然我國國家標準局(CNS560)已於107年4月將SD550W及SD690納入鋼筋混凝土用鋼筋，惟目前對於採用此鋼筋之續接器，即灌漿式螺紋續接套筒，其力學行為尚不清楚。
本文將採用ABAQUS有限元素分析軟體對SD690螺紋節鋼筋之灌漿式續接器於軸向拉力下之應力傳遞機制以及破壞形式進行研究，並對照試驗結果以驗證有限元素分析之準確性；接著針對不同長度之續接套筒進行比對，來探討增加套筒環節將會對力量傳遞上有何影響。 | zh_TW |
| dc.description.abstract | With densely-populated and limited land, new buildings are mostly developed towards high-rise buildings in Taiwan. The main technology is the use of high-strength screw-type deformed bars and its suitable coupling sleeve. High-strength steel bars refer to SD550W and SD690 with yield strengths of 550 MPa and 690 MPa stresses. Although SD550W and SD690 have been included as reinforcing bars for reinforced concrete by the National Standards of the Republic of China (CNS560) in April 2018, the mechanical behavior of the grout-filled coupling sleeve, which is used for screw-type deformed bars, is still unknown.
In this paper, ABAQUS finite element analysis software was used to study the mechanism of transferring stress and damage pattern of the grouting sleeve for SD690 screw-type deformed bars under axial tension. In addition, connectors with different lengths were compared to investigate the effect of the different threaded sleeves on the force transfer. | en_US |
