Earthquakes have caused over $1,000 billion of damage and more than 100,000 deaths in the last decade. This devastation occurred mainly in unreinforced brick masonry (URM) buildings which constitute the bulk of the domestic building stock in low seismicity regions, including Australia. These buildings were designed to resist forces, not the displacements, caused by earthquake ground shaking. This project will develop a new displacement-based method for assessing the earthquake resistance of URM buildings. Research outcomes will be in the form of improved analytical methods for the design of new buildings and the seismic assessment and retrofit of existing buildings.

在过去十年中，地震造成了超过1万亿美元的损失和10万多人死亡。 这种破坏主要发生在未加固的砖砌体（URM）建筑物中，这些建筑物构成了包括澳大利亚在内的低地震地区的大部分住宅建筑。 这些建筑物的设计是为了抵抗地震引起的地面震动，而不是位移。 该项目将开发一种新的基于位移的方法来评估URM建筑物的抗震能力。 研究成果将以改进分析方法的形式出现，用于新建筑物的设计以及现有建筑物的抗震评估和改造。
