Abstract

Structures made of Roller Compacted Concrete (RCC) may be subjected to dynamic loads during their service life. Understanding the dynamic material properties of RCC and the performance of RCC structures is essential for better analysis and design of RCC structures. As full-scale tests are often unaffordable, numerical simulation methods are continuously employed. However, in numerical simulations, determining a reasonable constitutive relationship for RCC materials is still limited due to the complexity of the composite and the special rolling and compacting construction technology. In this paper, the triaxial compressive test and split Hopkinson pressure bar (SHPB) experimental results for RCC are introduced as an experimental foundation. Parameter calibrations and modifications in terms of the strength yield surface, the strain rate effect and the failure criterion for the RCC materials are presented. Numerical verification is illustrated for simulating the SHPB experiment and predicting the dynamic compressive characteristics of RCC specimens with a modified HJC model. The results reveal that the simulation results for the modified model have better agreement with the test data than those with the model before modification and have better simulation results. Sensitivity studies of the key parameters on the yield surface of the modified HJC model are conducted to improve the simulation effect for numerically predicting the performance of RCC structures exposed to explosive and impact loads.

摘要

碾压混凝土（RCC）结构在其使用寿命期间可能会承受动态荷载。了解碾压混凝土的动态材料特性以及碾压混凝土结构的性能对于更好地分析和设计碾压混凝土结构至关重要。由于全尺寸试验通常成本过高，因此不断采用数值模拟方法。然而，在数值模拟中，由于碾压混凝土材料的复合材料复杂性以及特殊的碾压施工技术，确定合理的本构关系仍然存在局限性。本文介绍了碾压混凝土的三轴压缩试验和分离式霍普金森压杆（SHPB）试验结果，作为实验基础。给出了碾压混凝土材料在强度屈服面、应变率效应和破坏准则方面的参数校准和修正。通过用改进的HJC模型模拟SHPB试验并预测碾压混凝土试件的动态压缩特性进行了数值验证。结果表明，改进模型的模拟结果与试验数据的吻合度优于未改进模型，且具有更好的模拟效果。对改进的HJC模型屈服面上的关键参数进行了敏感性研究，以提高数值预测暴露于爆炸和冲击荷载下的碾压混凝土结构性能的模拟效果。
