Precast　columns　are　widely　adopted　in　Accelerated　Bridge　Construction　(ABC)　due　to　its　fast　construction　speed,　environment　amity　and　little　interference　to　existing　traffic.　The　bending　behavior　of　precast　columns　with　grouted　sleeve　connections　under　seismic　effect　has　been　widely　studied.　However,　studies　on　the　shear　behavior　of　this　kind　of　columns　(for　example,　short　columns　under　seismic　effect)　are　limited,　which　restricts　the　application　of　ABC　in　seismic　regions.　This　study　proposes　an　approach　for　evaluating　the　shear　cracking　mechanism　of　sleeve　region　and　the　shear　strength　of　precast　columns　with　grouted　sleeve　connection.　In　this　approach,　the　sleeve　units　and　concrete　units　in　the　sleeve　region　are　established　according　to　the　different　stiffness　between　sleeve　and　concrete,　individually.　The　cracking　angle　of　membrane　element　of　units　is　solved　based　on　the　Modified　Compression　Field　Theory　(MCFT).　Thus,　the　crack　developing　diagram　is　drawn　in　light　of　the　cracking　range　of　units.　An　improved　model　for　computing　the　shear　strength　of　precast　columns　with　grouted　sleeve　connection　is　presented　by　the　predicted　cracking　method　in　this　paper.　A　skeleton　curve　prediction　method　based　on　the　principal　compressive　strain　in　compression　zone　has　also　been　proposed　and　verified.　In　general,　the　improved　MCFT　method　given　in　the　paper　is　effective　for　predicting　shear　failure　of　precast　bridge　columns　with　sleeve　connection.
