摘要
阐明钢筋受压屈曲的概念,从单根钢筋和钢筋混凝土柱纵筋两个方面对地震作用下钢筋混凝土柱纵筋屈曲的研究进展进行论述。分析影响钢筋屈曲的主要因素,介绍具有代表性的几个考虑屈曲的钢筋本构模型;讨论纵筋屈曲试验研究中存在的问题及解决方法,论述考虑纵筋屈曲的钢筋混凝土柱设计及抗震性能数值分析方法。最后,总结出纵筋屈曲需要进一步研究的问题。
The concept on buckling of reinforcing bars in compression is clarified. The researches on buckling of both single reinforcing bar and longitudinal bars in RC columns under earthquake excitation are reviewed. The major influencing factors on buckling of reinforcing bars are analyzed, and then several typical constitutive models considering buckling of reinforcing bars are introduced. Some unsolved problems in buckling experiment of reinforcing bars and their potential solutions are discussed. Furthermore, the design and the numerical analysis methods for seismic performance of RC columns considering the buckling of longitudinal bars are described. Finally, some research topics on buckling of longitudinal bars deserving further efforts are summarized.
