Even\nif this practice is safe, it may not be the most economical. In order to economically restore and improve\nour existing infrastructure, the engineering community needs to be able to assess the potential gains associated\nwith reducing epistemic uncertainties using measurements, before opting for costly intervention\nactions, if they become necessary. This paper provides a pre-posterior analysis framework to (1) optimize\nsequences of actions minimizing the expected costs and satisfying reliability constraints, and (2) quantify\nthe potential gain of making measurements in existing structures. Illustrative examples show that when\nthe failure probability estimated based on the present state of knowledge does not satisfy an admissible\nthreshold, strengthening or replacement interventions can be sub-optimal first actions. An example shows\nthat significant savings can be achieved by reducing epistemic uncertainties.","language":"en"},{"key":"dc.language.iso","value":"eng","language":"en"},{"key":"dc.rights","value":"Attribution-NonCommercial-NoDerivs 2.5 Canada","language":null},{"key":"dc.rights.uri","value":"http:\/\/creativecommons.org\/licenses\/by-nc-nd\/2.5\/ca\/","language":null},{"key":"dc.title","value":"Pre-posterior optimization of sequence of measurement and intervention actions under structural reliability constraint","language":"en"},{"key":"dc.type","value":"Text","language":"en"},{"key":"dc.type.text","value":"Conference Paper","language":"en"},{"key":"dc.description.affiliation","value":"Non UBC","language":"en"},{"key":"dc.description.reviewstatus","value":"Unreviewed","language":"en"},{"key":"dc.description.notes","value":"This collection contains the proceedings of ICASP12, the 12th International Conference on Applications of Statistics and Probability in Civil Engineering held in Vancouver, Canada on July 12-15, 2015.
