High Strength Steel Protection Bollards

恐怖袭击给澳大利亚人带来了巨大的痛苦和数百万美元的损失。预防攻击是最重要的。被动道路护柱通常用于阻止车辆接近和/或进入安全敏感的基础设施。薄壁管被用来制造这种护柱。然而，对于它们的行为，特别是高强度合金钢护柱在受到冲击载荷时的行为，人们缺乏了解。研究人员将运用他们在薄壁管状结构方面的广泛知识，建立设计高强度护柱的最经济的方法。这些知识将被转移到设计标准和澳大利亚有限的国防资源中。

Terrorist attacks cost Australians much human grief and millions of dollars. Prevention of an attack is paramount. Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards. However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads. The investigators will apply their extensive knowledge in thin-walled tubular structures to establish the most economical means of designing high strength bollards. This knowledge will be transferred into design standards and Australia's limited defence resources.
