SMAR 2024 – 7th International Conference on Smart Monitoring, Assessment and Rehabilitation of Civil Structures Random Finite Element Reliability Assessment of Existing Concrete Structures – Case Studies and Research Direction Fadi Oudah a,b *, Glen Norlander b a Associate Professor, Dalhosuie University, Halifax, Nova Scotia, Canada b Principal, Norlander Oudah Engineering Limited (NOEL), Calgary, Alberta, Canada Abstract The material properties of concrete and reinforcing steel in reinforced concrete structures vary spatially across the structural dimensions due to the inherent heterogeneous nature of concrete. The spatial variation is further affected by active deterioration mechanisms such as freeze thaw damage, alkali silica reactivity, and corrosion of the reinforcing steel as all of these mechanisms are random. The spatial variation of concrete mechanical properties (compressive strength, tensile strength, modulus of elasticity) and corrosion effect of reduced section loss influence the structural reliability, and hence, the structural risk. Random finite element (RFE) simulation has been recently employed in engineering consultancy to assess structures with spatially varying properties using reliability analysis. The objectives of this paper are to 1) document the application of RFE in real-life case studies of structural reliability assessment projects conducted by the authors in Canada, and 2) provide recommendations for future research to improve the practicality of analysis for consulting jobs. The paper will provide readers with insight into the application of advanced methods of analysis in consulting work for risk-based condition assessment of critical infrastructure. Recommendations for future research and analysis refinements are discussed. a b © 2024 The Authors. Published by Elsevier B.V.
