Traditional inspections often fail to detect these early-stage flaws, leaving structures vulnerable to unexpected deterioration. This study presents a structural performance monitoring methodology that combines high-resolution distributed fiber optic sensors (DFOS) with static load testing. DFOS provides continuous strain and temperature profiles, capturing global structural behavior and detecting localized effects often missed by conventional approaches. Applied to a full-scale prestressed concrete bridge in Switzerland, the method enabled accurate insight on the bridge structural response.\n","rp_start_date":"2024-06-01 14:48:00","rp_duration":36,"rp_main_funder":"FNR","rp_other_funders":[],"rp_external_partners":["Federal Polytechnic School of Lausanne (EPFL)","Federal Institute of Technology Zurich (ETH)","Graz University of Technology (TUGraz)","IRMOS","Swisslnspect"],"rp_keywords":["Distributed fiber optic sensors","Structural identification","Structural performance monitoring","Concrete bridge","Load testing","Structural health monitoring"],"rp_members":[{"name":"Francesco FABBRICATORE","isPI":true,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwODUwNDdfX0ZyYW5jZXNjbyBGQUJCUklDQVRPUkU=","detailsPageUrl":"https:\/\/www.uni.lu\/fstm-en\/people\/francesco-fabbricatore\/","id":"50085047"},{"name":"Numa Joy BERTOLA","isPI":false,"isExternal":false,"featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwNzM1MDJfX051bWEgSm95IEJFUlRPTEE=","detailsPageUrl":"https:\/\/www.uni.lu\/fstm-en\/people\/numa-joy-bertola\/","id":"50073502"}]},"research-project-status":[275],"research-project-type":[267],"field-of-interest":[287],"organisation":[47,29,64],"authorship":[379],"acf":[],"_links":{"self":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches\/41862"}],"collection":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches"}],"about":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/types\/core-researches"}],"author":[{"embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/users\/379"}],"version-history":[{"count":1,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches\/41862\/revisions"}],"predecessor-version":[{"id":41864,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches\/41862\/revisions\/41864"}],"wp:authorship":[{"embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/users\/379"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/media\/41863"}],"wp:attachment":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/media?parent=41862"}],"wp:term":[{"taxonomy":"research-project-status","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/research-project-status?post=41862"},{"taxonomy":"research-project-type","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/research-project-type?post=41862"},{"taxonomy":"field-of-interest","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/field-of-interest?post=41862"},{"taxonomy":"organisation","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/organisation?post=41862"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
