Research Progress and Comment on Seismic Deformation Capacity of Reinforced Concrete Piers

为研究影响钢筋混凝土墩柱抗震变形能力的因素,分析了配箍特征值、轴压比、纵筋配筋、剪跨比、混凝土保护层厚度等5个因素对钢筋混凝土墩柱地震变形能力的影响,总结了以墩柱极限位移角作为变形能力衡量指标时,不同因素对墩柱变形能力的影响。相关结论可为未来的研究提供参考。

In order to study the factors that affect the seismic deformation capacity of reinforced concrete piers, the influence of five factors, such as stirrup characteristic value, axial compression ratio, longitudinal reinforcement, shear span ratio and concrete cover thickness, on the seismic deformation capacity of reinforced concrete piers is analyzed. The influence of different factors on the deformation capacity of piers is summarized when the ultimate displacement angle of piers is taken as the deformation capacity measurement index. The relevant conclusion can provide reference for future research.
