摘要

对钢筋混凝土结构意外碰撞情景的理解和评估是安全问题的重要内容。虽然这一课题的实验研究已经有了很长的成功历史，但就数值模拟而言，仍有许多问题有待解决。本文研究了Abaqus混凝土损伤塑性(CDP)模型的一些特点，以期有效地将CDP模型应用于钢筋混凝土结构的冲击荷载模拟中。特别地，研究了模拟响应对模型参数和单元尺寸的敏感性。将模拟响应与钢筋混凝土板基准冲击试验结果进行了比较。

Using the Abaqus CDP model in impact simulations

The understanding and assessment of accidental crash scenarios on reinforced concrete structures is of high interest for safety issues. Although experimental research on this topic has already a long and successful history, there are many issues waiting to be solved as far as numerical simulations are concerned. In this article some particularities of the Abaqus Concrete Damaged Plasticity (CDP) model are investigated with the purpose of using efficiently the CDP model in impact loaded reinforced concrete structure simulations. In particular, the sensitivity of the simulation response with respect to model parameters and element size is studied. The simulation response is compared to measurements from benchmark impact tests on reinforced concrete plates.
