This project aims to develop a displacement-based method of assessing precast concrete buildings in regions of lower seismicity for risk of collapse and seismic performance. The project will investigate the system behaviour and vulnerability of buildings laterally supported by precast concrete geometric walls, which are currently poorly understood but dominate Australian construction. The modelling produced is expected to allow such buildings to be simply checked for seismic compliance using displacement principles, rather than the more complex force based methods with direct benefits for building costs and community safety.

该项目旨在开发一种基于位移的方法来评估地震活动较低地区的预制混凝土建筑的倒塌风险和抗震性能。该项目将调查由预制混凝土几何墙横向支撑的建筑的系统行为和脆弱性，目前人们对此知之甚少，但在澳大利亚的建筑中占主导地位。预计制作的模型将允许使用位移原理简单地检查此类建筑的抗震符合性，而不是更复杂的基于力的方法，对建筑成本和社区安全有直接好处。
