- Description
- This paper presents the conceptual framework for developing structural assessment and risk estimation procedures based on sound structural engineering, modern methods of structural analysis and on-site inspection and modern risk assessments practices, including non-destructive techniques. The framework is intended to be used by Government agencies or private parties as a basis for risk assessment of existing and of new masonry construction. The framework as outlined herein will translate the findings of various research strands into practical tools and recognises the gradual improvement over time of metal wall fitments that stabilise brickwork. Controlled laboratory and experimental field-based metal fitment corrosion data will be benchmarked against in-situ building inspection data to inform numerical modelling and development of ‘fragility curves’. These curves express the probability of sudden wall collapse versus factors relating to building condition, the local brickwork cavity environment, and natural hazard load events including wind loads and peak ground earthquake acceleration. The relationship between fragility curves and the outputs to be expected from dynamic excitation and response measurements will be quantified using established and new non-destructive techniques. The influence of environmental parameters on wall fragility, such as higher air pollution levels, or atypical extended time of wetness due to higher-than average annual rainfall, will also be investigated. Recommendations will be made regarding the intensity of excitation and the degree to which responses need to be measured to provide sufficiently accurate predictions of structural long-term capacity.
