T　Substantial　studies　have　been　conducted　on　the　force　analysis　and　design　issues　of　the　anchorage　zone　of　prestressed　concrete　structure　and　significant　discrepancies　exist　within　different　methodologies　and　the　respective　results　in　different　countries.　In　the　proposed　research,　local　stress　of　the　anchorage　zone　of　single-eccentric　straight　anchor　with　rectangular　section　was　analysed　and　the　effect　of　pressure-bearing　ratio　λ　and　eccentricity　γ　on　the　stress　distribution　in　the　anchorage　zone　was　studied.　Based　on　the　stress　analysis,　the　single-eccentric　straight　anchor　was　categorised　into　small　eccentricity,　large　eccentricity　and　critical　eccentricity.　The　respective　strut-and-tie　design　model　was　proposed.　Finally,　equations　to　predict　the　cracking　load　of　single-eccentric　straight　anchor　were　proposed　and　verified　by　comparing　the　results　based　on　the　experiments.　©　2016　Taylor　&　Francis　Group,　London.
