- 摘要:
- 在爆炸荷载作用下为比较HJC和K&C混凝土模型分析混凝土力学性能的准确性,基于这两种模型的物态方程参数和强度模型参数对钢筋混凝土梁在爆炸荷载作用下的动力响应进行了数值分析.研究结果显示,在爆炸荷载作用下应用K&C混凝土模型分析混凝土力学性能的准确性显著优于HJC模型,因此本研究结果可为爆炸荷载作用下分析混凝土的力学性能提供理论参考.
- Abstract:
- To compare the mechanical properties accuracy of HJC and K&C concrete models under explosion, the dynamic response of reinforced concrete(RC)beams under blast load is numerically analyzed based on the comparison between their state of equation parameters and strength model parameters. The results show that the accuracy of using K&C concrete model to analyze the mechanical properties of concrete under explosion is significantly better than that of HJC model. The research results can provide reference for precise mechanics analysis of concrete structures under explosion.
