摘要

摘要:
为探究端承式部分填充混凝土的预制拼装钢桥墩（PS-PFC）的抗震性能，在已有研究的基础上，以混凝土填充率为参数，增加了2个填充率分别为0和50%的大比例试件的拟静力试验，并通过ABAQUS进行了该类桥墩的有限元模拟与拓展参数分析。试验结果表明：端承式PS-PFC到达极限状态时的共同破坏形态表现为柱底钢板的弯曲变形和锚杆的拉伸变形，此外，未填充混凝土的桥墩还出现了柱底加劲肋上方钢管的鼓曲和撕裂，这说明部分填充混凝土能有效遏制钢管局部屈曲的发生；该类桥墩的滞回曲线呈较为饱满的捏拢状，具有良好的抗震性能；当填充率由0增加至25%时，桥墩的弹性刚度增加了9.5%，水平承载力增加了17.1%，继续增加填充率至50%，试件的刚度和承载力未见明显变化；与未填充混凝土的桥墩相比，填充率为25%和50%的桥墩的累积滞回耗能增加了约88%，并表现出更强的抗强度退化和刚度退化的能力；有限元模拟结果与试验结果吻合较好，桥墩的抗震性能随混凝土填充率的增大有所提升，然而当填充率增加到一定程度时，继续填充混凝土对桥墩水平承载力的影响并不显著；提出的端承式PS-PFC弹性刚度、水平承载力和最优混凝土填充率的理论计算方法，计算结果与试验结果和有限元模拟结果吻合良好。

Abstract:
This paper aims to investigate the seismic performance of end-bearing prefabricated steel bridge piers with partially filled concrete (PS-PFC). Based on existing research, two large-scale specimens with concrete filling ratios of 0 and 50% were added for quasi-static tests by employing the concrete filling ratio as a parameter. Additionally, finite element simulations and extended parametric analyses of such piers were performed by adopting ABAQUS software. The results show that the common failure mode of the end-bearing PS-PFC in the ultimate state is characterized by the bending deformation of the column base plate and tensile deformation of the anchor rods. Additionally, piers without filled concrete exhibit bulging and tearing of the steel tube above the stiffeners at the column base, indicating that partially filled concrete can effectively suppress local buckling of steel tubes. The hysteresis curves of such piers are relatively full and pinched, indicating good seismic performance. When the filling ratio increases from 0 to 25%, the elastic stiffness and horizontal bearing capacity of piers increase by 9.5% and 17.1%, respectively. Further increasing the filling ratio to 50% produces no significant changes to the specimen's stiffness and bearing capacity. Compared with piers without filled concrete, bridge piers with 25% and 50% filling ratios exhibit an approximately 88% increase in cumulative hysteretic energy dissipation, and demonstrate enhanced resistance to both strength degradation and stiffness degradation. The finite element simulations show good agreement with the experimental results, and the seismic performance of bridge piers improves with the increasing concrete filling ratios. However, when the filling ratio reaches a certain threshold, its further increase has a negligible effect on the horizontal bearing capacity of bridge piers. The proposed theoretical calculation methods for the elastic stiffness, horizontal bearing capacity and optimal concrete filling ratio of end-bearing PS-PFC yield results in good agreement with the test results and finite element simulation results.
