中文摘要 | 本研究之目的在於建立一理論模式,使其能移用來預測以彎鈎形式錨定於鋼筋混接土梁控外接頭中之梁主筋在重複載重作用下之載重與滑移關係。本研究係利用 (1) 單向拉載重及重複拉載重作用下鋼筋之應力與應變關係,(2) 單向拉載重、重複拉載重及反覆載重作用下鋼筋之局部握裹應力與滑移關係,(3) 單向拉載重及重複拉載重作用下,彎鈎鋼筋彎鈎起點之鋼筋應力與滑移關係,(4) 沿著鐵筋方向力量之平衡關係及位移之諧合關係,以預測重複載重作用下彎鈎鋼筋之載重與滑移關係。由理論模式所預測之結果並用來和試驗結果作一比較,以檢核理論模式之可靠性。本研究中所探討之參數包括混凝土抗壓強度、鋼筋之降伏強度、鋼筋之大小、載重歷程及鋼筋之錨定方式。 |
英文摘要 | This paper is to develop an analytical model for predicting the load-slip relationships of booked reinforcing bars anchored within exterior beam-column joints and subjected to repeated loading. The model is developed by utilizing (1)the stress-strain characteristics of reinforcing bars under monotonic and repeated tensile loading, (2) the local bond stress-slip relations of reinforcing bars subjected to monotonic loading, repeated tensile loading and reversed cyclic loading separately; (3)the steel stress-slip relationships for the beginning point of the bent portion of hooked reinforcing bars under repeated pull loading, and (4) the equilibrium of forces and the compatibility of displacements along the anchorage length of the bar. |
