项目摘要

In 1998, to clarify stress transferring mechanism of the joint connected reinforced concrete member with the steel member in series, four specimens were tested. All specimens had reinforced concrete member with a section of 2000×300 mm and the steel member with a flange width of 100 mm and a depth of 200 mm. The transverse reinforcement ratio in the joints was 0.64% for all specimens. Experimental variable was the length of the steel member embedded in the reinforced concrete member. The length of the embedded steel member was 200, 400, 600 and 800 mm. Pure bending was applied at the joint. From the test results, the following remarks can be drawn ; 1) The mechanism of stress transfer from the steel member to the reinforced concrete member was clarified theoretically. 2) On the basis of this mechanism, a method capable of predicting the ultimate strength was proposed. 3) The predictions were shown to be in good agreement with the test results. 4) From test result, it was shown that the … More embedded length of three times the depth of the steel member is necessary to develop the ultimate flexural strength of the member.In 1999, three joint details were proposed to improve performance of the joint with short embedded length. Joint details with additional transverse reinforcing bars at the beginning and the end of the embedded steel member, and plate welded at the end of the embedded steel member and additional longitudinal and transverse reinforcing bars were proposed. Furthermore, joint detail with diagonal reinforcing bars at the reinforced concrete part of the joint was also proposed. To verify the effectiveness of proposed joint details, four specimens were tested. The dimensions and reinforcement of the member were similar to the specimens carried out in 1998. From test result, it was shown that additional transverse reinforcing bars at the beginning and the end of the embedded steel member and plate welded at the end of the embedded steel member were effective to increase the ultimate strength of the joint.

1998年,为明确钢筋混凝土构件与钢构件串联接头的应力传递机理,对4个试件进行了试验。所有试件均采用截面为2000×300mm的钢筋混凝土构件和翼缘宽度为100mm、深度为200mm的钢构件。所有样本的接缝横向配筋率为 0.64%。实验变量是嵌入钢筋混凝土构件中的钢构件的长度。预埋钢构件的长度为200、400、600和800毫米。在接头处应用纯弯曲。从测试结果可以得出以下结论: 1)从理论上阐明了应力从钢构件向钢筋混凝土构件传递的机理。 2)基于该机理,提出了一种能够预测极限强度的方法。 3) 预测结果与测试结果非常吻合。 4) 试验结果表明,为了提高构件的极限抗弯强度,需要三倍于钢构件深度的埋入长度。1999年,提出了三种节点细节,以提高埋入长度较短的节点的性能。提出了在预埋钢构件的开始和末端附加横向钢筋、在预埋钢构件末端焊接板以及附加纵向和横向钢筋的接头细节。此外,还提出了在接头的钢筋混凝土部分使用对角钢筋的接头细节。为了验证所提出的接头细节的有效性,对四个样本进行了测试。构件的尺寸和配筋与1998年的试件相似。试验结果表明,在预埋钢构件首尾加设横向钢筋以及在预埋钢构件端部焊接钢板,对于提高节点的极限强度是有效的。较少的
