There　are　cases　where　the　common　approaches　used　to　assess　the　temperature　loading　effects　may　not　be　sufficient,　especially　in　the　case　of　integral　abutment　bridges　(IABs).　In　IABs,　the　incorrect　choice　of　the　design　temperature　may　result　in　an　unwanted　tensional　state　in　the　bridge　decks　and　additional　loads　on　the　abutments.　For　post-tensioned　bridges,　the　combined　effects　of　excessive　temperature　loads　and　loss　of　tension　in　the　post-tensioned　cables　due　to　time-dependent　phenomena　like　relaxation　in　steel　and　shrink-age　and　creep　in　concrete　may　lead　to　probabilities　of　exceedance　of　serviceability　(or　ultimate)　limit　states　that　exceed　the　code　specifications　and/or　desired　levels　of　safety,　and　to　cascading　negative　effects　on　the　operation　of　the　road　infrastructure.　This　research　aims　at　assessing　the　sensitivity　of　IABs　to　the　long-term　effects　of　temperature　loads　and,　in　a　second　step,　quantifying　the　probability　of　exceedance　of　relevant　serviceability　limit　states.　©　2023　Ernst　&　Sohn　GmbH.
