The effect of Mo addition on the precipitation of carbides both in austenite and ferrite of Nbbearing HSLA steel were investigated by stress relaxation and transmission electron microscopy(TEM).Experimental results showed that the addition of~0.2 wt.%Mo into Nb-bearing steel slightly accelerated the precipitation kinetics of Nb carbides both in austenite and ferrite.The particles,(Nb,Mo)C,precipitated in Nb-Mo-bearing steel exhibit superior coarsening resistance compared to that of NbC particles in Nb-bearing steel.And the difference of carbides precipitated in anstenite and ferrite of Nb-Mo-bearing steel was discussed.

CFRP与钢表面的良好粘接是保证钢结构加固效果的关键.本文进行了CFRP板-钢界面粘结性能的试验研究,试验采用单剪界面形式,研究了胶层厚度、胶层类型等参数对粘接强度的影响,分析了失效模式、粘结强度、CFRP板应变、界面剪应力、粘结-滑移等参数的变化规律.试验结果表明,随着胶层厚度的增加,界面粘结强度逐渐变大;胶层类型对界面粘结强度影响显著,Araldite2015胶试件具有更高的粘结强度;Sika
本文基于对抗剪加固FRP的破坏全过程分析,得到了带锚固U型FRP加固T型RC梁FRP拉断破坏时极限状态下FRP的应力分布状态,并在此基础上推导出考虑T型RC梁翼缘影响的FRP有效应力表达式及FRP抗剪强度模型.然后搜集了带锚固U型FRP加固T型RC梁FRP拉断破坏时试验梁数据,并将本文提出的抗剪强度模型预测结果与上述试验数据进行了比较.对比结果表明本文所提出的FRP抗剪强度模型具有较高准确性,相比
采用外贴FRP或附加粘滞阻尼器方式对钢筋混凝土框架结构进行加固,可有效改善结构的抗震性能.为比较分析两种加固形式及不同加固方案对多层钢筋混凝土框架结构抗震性能的影响,本文基于OpenSees有限元分析平台,对FRP或附加粘滞阻尼器加固前后的多层钢筋混凝土框架结构模型进行了弹塑性动力时程反应分析.分析结果表明:FRP加固后提高了结构的变形及抗震能力,但并不能减小结构的位移响应,而采用粘滞阻尼器加固则
在上世纪80年代前后,我国建成了较多的钢筋混凝土T梁桥,这类T梁桥经过多年的营运,已经出现了较多的病害,其加固方法值得研究.本文以一座20米钢筋混凝土T梁桥的加固设计为基础,进行了多个加固方案的对比,计算表明,采用预应力碳纤维板和增厚翼板的组合加固法,不但可以大幅度提高T梁的承载力能力,而且加大的预应力碳纤维,可以提供更多的预拉力,改善T梁的使用性能;此外增厚的翼板混凝土与其它T梁横向联系加固措施

盾构隧道在运营过程中由于种种原因发生过量的纵向沉降或不均匀沉降,引发隧道渗水漏泥、结构局部破坏,或内部结构(如地铁轨道)发生纵向扭曲变形,而影响隧道的正常运营.目前,很多隧道加固研究是加固隧道断面,只有较少学者对隧道纵向进行过加固研究,本文采用CFRP网格加固盾构隧道进行缩尺模型试验.试验结果表明,盾构隧道纵向等效抗弯刚度有效提高,达到加固补强的作用.
