This project aims to investigate and quantify the role of spatial variability of material properties in the failure behaviour and safety of unreinforced masonry shear walls. In masonry buildings, shear walls provide the primary means for safely resisting lateral loads due to wind and earthquake. Failure of the shear walls can result in building collapse causing injuries and death and significant economy losses. Through experimental testing and numerical modelling the project will enable improved techniques for the assessment and design of masonry walls which account, for the first time, for the influence that spatial variability of material properties has in determining the failure behaviour and capacity of masonry shear walls.

本项目旨在调查和量化材料特性的空间变异性在无筋砌块剪力墙的破坏行为和安全性中的作用。在砖混结构建筑中，剪力墙提供了安全抵抗风和地震引起的横向荷载的主要手段。剪力墙的破坏会导致建筑物倒塌，造成人员伤亡和重大的经济损失。通过实验测试和数值模拟，该项目将使评估和设计砌块墙的技术得到改进，首次考虑到材料特性的空间变异性对确定砌块剪力墙的破坏性能和能力的影响。
