Abstract：

In　order　to　study　the　fatigue　reliability　of　pre-stressed　concrete　simple-supported　beams　that　considered　the　effect　of　size　effect,　using　the　existing　method　to　check　the　fatigue　reliability　of　the　test-piece.　The　fatigue　test　of　three　pre-stressed　concrete　simple　beams　was　carried　on,　which　the　size　of　the　beams　was　different,　and　collected　the　data　of　the　fatigue　test.　Used　hierarchical　checking　method,　a　second-order　moment　method　to　check　the　reliability　of　the　beams,　compared　the　results　of　fatigue　reliability　which　calculated　by　two　different　checking　methods.　Analyzed　and　summarized　the　effect　of　size　effect　on　fatigue　reliability.　©　2020　IOP　Publishing　Ltd.　All　rights　reserved.
