Stochastic hazard assessment of unreinforced masonry wall systems

本项目旨在更好地了解墙体系带对结构性能和砌体墙体系统可靠性的影响。对新建筑和现有建筑的结构可靠性进行比较，将提供现有设计标准是否不一致、在某些情况下过于保守或在另一些情况下不谨慎的定量证据。能够更准确地评估现有砖石结构的安全性，很可能使当局能够避免对此类结构进行不必要的拆除或修复，或正确地确定何时需要采取此类措施。更有效地使用结构砌体可以减少温室气体排放，增强建筑的可持续性。

This project aims to develop an improved understanding of the effects of wall-ties on structural behaviour and reliability of masonry wall systems. A comparison of structural reliabilities for new and existing construction will provide quantitative evidence of whether or not existing design criteria are inconsistent, too conservative in some cases, or incautious in others. The ability to more accurately evaluate the safety of existing masonry structures will likely allow authorities to avoid unnecessary demolition or rehabilitation of such structures, or to correctly identify when such measures are essential. A more efficient use of structural masonry can reduce greenhouse gas emissions and enhance the sustainability of construction.
