Structural safety and reliability of unreinforced masonry shear walls

该项目旨在调查和量化材料性能的空间变异性在未加筋砌体剪力墙的破坏行为和安全中的作用。在砖石建筑中，剪力墙是安全抵抗风和地震引起的侧向荷载的主要手段。剪力墙的破坏可导致建筑物倒塌，造成人员伤亡和重大经济损失。通过实验测试和数值模拟，该项目将改进砌体墙的评估和设计技术，首次考虑材料特性的空间变异性在决定砌体剪力墙的破坏行为和能力方面的影响。

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.
