Steel lattice towers find widespread use as structural components in electricity transmission systems and as base towers in UHF and microwave communications networks. They tend be protected from bushfire damage by active backburning or clearing through their easement or right of way, because the response of towers to bushfires is surprisingly unknown, and it is not known if they can provide passive protection without clearing/backburning. A world first, this Project aims to use advanced numerical techniques to assess the fragility and resilience of lattice towers in fire using a systems approach based on fire load data available with a further goal to explore potential pragmatic strengthening strategies if necessary and feasible.

钢网架铁塔在电力传输系统中被广泛用作结构部件，在超高频和微波通信网络中也被用作基塔。它们往往通过主动回燃或通过地役权或通行权清除来保护自己免受丛林火灾的伤害，因为塔楼对丛林火灾的反应令人惊讶地未知，也不知道它们是否能够在没有清除/回燃的情况下提供被动保护。作为世界上第一个项目，该项目旨在使用先进的数值技术，使用基于现有火灾载荷数据的系统方法来评估格构塔在火灾中的脆弱性和恢复力，并在必要和可行的情况下探索潜在的实用加固策略。
