Displacement-based assessment of the seismic resistance of unreinforced masonry 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无加固砖砌体（URM）建筑中，这些建筑构成了包括澳大利亚在内的低地震活动性地区的大部分住宅建筑。这些建筑的设计是为了抵抗地震引起的地面震动而不是位移。本项目将开发一种新的基于位移的方法来评估URM建筑的抗震性能。研究成果将以改进新建筑物设计的分析方法和现有建筑物的地震评估和改造的形式出现。

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.
