矩形空心墩滞回性能模拟的统一计算模型
|
摘要
建立了不同破坏模式下矩形空心墩抗震变形能力的统一计算公式,并将其应用于矩形空心墩抗震的滞回分析模型,通过7个不同破坏形态矩形空心墩柱对滞回分析模型进行了验证,对保证大型桥梁工程抗震安全具有重要意义。
The paper establishes the unified calculation model for the anti-seismic deformation capacity of the rectangular hollow piers in various damage models,applies it into the anti-seismic hysteretic analysis model of the rectangular hollow pier,and proves the hysteretic analysis model of rectangular hollow piers with 7 damages,so it is significant to ensure the anti-seismic safety of large bridge projects.
