Estimation method and device for beam falling prevention effect

The invention provides an estimation method and device for a beam falling prevention effect. The estimation method comprises the steps: building a power space calculation model according to a target pier structure; inputting boundary conditions into the power space calculation model, and determining a first parameter model; inputting a collision simulation condition into the first parameter model,and determining a second parameter model; and inputting actual seismic wave data into the second parameter model, and determining the anti-beam-falling effect of the target pier structure. Accordingto the estimation method, the final collision simulation model is determined through three-stage modeling, and the anti-beam-falling effect of actual seismic wave data can be effectively and accurately evaluated. 本发明提供了一种防落梁效果的估计方法及装置，其中该方法包括：根据目标桥墩结构，建立动力空间计算模型；将边界条件输入至所述动力空间计算模型，确定第一参数模型；将碰撞模拟条件输入至所述第一参数模型，确定第二参数模型；将实际地震波数据输入所述第二参数模型，确定所述目标桥墩结构的防落梁效果。本发明通过三阶段建模确定最终的碰撞模拟模型，能够对实际地震波数据的防落梁效果进行有效准确的评估。
