研究表明，当两块钢板用多根碳纤维粘结在一起时，靠近钢板一侧的碳纤维应力往往较大。这种倾向可能发生在用接线板加固的腐蚀高强度螺栓摩擦接头上。本文对拼接板和接线板的节点进行了有限元分析和拉伸试验，重点研究了拼接板和接线板上的轴向力。有限元分析结果表明，拼接板上的轴向力分担比按拼接板和接线板的截面积之比计算的轴向力大约10%。拉伸试验结果也显示出与有限元结果相同的趋势。
It has been clarified that the stresses in the carbon fiber on the closer side to the steel plate tend to be higher when two steel plates are bonded together with multiple carbon fibers. This tendency might occur in corroded high-strength bolt friction joints retrofitted by the patch plates. In this study, finite element analysis and tensile tests were conducted on a joint with the splice and patch plates, focusing on the axial force on the splice and patch plates. The results of the finite element analysis revealed that the axial force sharing on the splice plate was about 10% higher than that calculated from the ratio of the cross-sectional area of the splice and patch plates. Tensile test results also showed the same tendency as FE results.
