To address the issue of bridge collisions induced by earthquakes, seismic vulnerability curves for the overall system and individual components of conventional and irregular box girder highway bridges, with and without collisions, were developed and compared based on nonlinear time history analysis using the OpenSees finite element software. Four damage states, ranging from minor to severe, were established. The fragility function was employed to elucidate the interaction between structural irregularities and collisions between the bridge deck and the abutment on the seismic vulnerability of multi-span box girder highway bridges. A conversion coefficient, rp, was introduced to quantify the impact of collisions on the vulnerabilities of bridge components and the overall system. Traditional analysis methods, including static and simplified analyses, alongside technical seismic models, were applied to adjust the vulnerability values associated with collisions and irregularities. The findings reveal that collisions exert adverse effects on all structural components. As the damage level increase, the variability in RP values for the ductility of bridge columns and anti-falling beams also increase. Specifically, for earthquake number 2, the rp values under damage conditions are 0.95 for mild(DC1) and 1.02 for moderate(DC2). Under pulse type seismic motion, collisions significantly increase the degree of damage to engineering demand parameters (EDP). For earthquake number 3, the average rp value for foundation translation was 0.71 with collisions and 0.57 without, highlighting the significant destructive influence of collisions on foundation translation. By comparing the median values across all categories, it was observed that the median values for earthquake numbers 3 and 1A were lower than those for earthquake numbers 2 and 1B, indicating that collisions caused more severe damage under lower ground motion intensities. This study provides a valuable reference for seismic bridge design, offering insights to improve design specifications, enhance the seismic performance of bridge structures, and deliver significant engineering and practical applications.

为解决地震引起的桥梁碰撞问题,基于OpenSees有限元软件的非线性时程分析,开发并比较了有无碰撞两种情况下常规和不规则箱梁公路桥梁的整体系统及各个组件的地震脆弱性曲线。研究设定了4种损伤条件,从常规到严重。通过脆弱性函数,阐明了不规则性和桥面板与桥台之间的碰撞对多跨箱梁公路桥梁地震脆弱性的交互作用。同时引入了转换系数rp,明确了冲击碰撞对桥梁组件及整体系统脆弱性的影响,应用了传统分析方法(静态与简化分析)和技术地震模型,调整了碰撞和不规则性的脆弱性值。研究结果表明:碰撞对所有结构组件都有不利影响。随着损伤等级的增加,桥柱延性和防落梁的rp离散性增加。地震编号2中,轻微(DC1)损伤条件下的rp为0.95,而中等(DC2)为1.02。在脉冲型地震动下,碰撞显著增加了工程需求参数(engineering demand parameter,EDP)的损害程度,编号3中,有碰撞时基础平移的平均rp为0.71,而无碰撞为0.57,表明了碰撞对基础平移的破坏作用显著。通过对所有类别的中值比较,发现地震编号3和编号1A的中值小于地震编号2和编号1B的中值,表明了在较低的地震动强度下,碰撞导致的损伤更为严重。研究结论为桥梁抗震设计提供了重要的参考依据,有助于改进设计规范,增强桥梁结构的抗震性能,具有重要的工程意义和实际应用价值。
