从实车碰撞试验、混凝土结构及构件抗侧向冲击试验模拟和数值模拟研究等方面系统总结国内外学者在钢筋混凝土(RC)柱抗车辆冲击问题的最新进展。在此基础上,分析现有落锤试验技术在研究车辆冲击问题中的不足,针对柱易遭受车辆碰撞部位冲击加载的试验方法,提出采用可溃缩变刚度锤头模拟车辆碰撞。在RC柱抗车辆冲击分析中,混凝土本构模型参数在低速冲击条件下的动态校准,车辆冲击荷载的合理简化也应是今后研究的重点。
The latest developments of reinforced concrete columns anti-vehicle impact issues are summarized and analyzed with reference to real car crash tests, anti-lateral impact test of concrete structure and components, and numerical simulation studies. Base on the existing shortage of drop hammer impact test technique in the research of vehicle collision with RC columns issues, an innovative technique for applying impact force on vulnerable part of RC columns with crushable and variable stiffness drop hammer is proposed. According to the analysis of RC columns collision with vehicle, dynamic optimization of concrete constitutive model under low velocity impact condition and reasonablly simplified load of vehicle impact should also be the focus of future research.
