The　deterioration　of　bridges　caused　by　heavy　traffic　and　aggressive　environment　becomes　increasingly　significant,　which　results　in　a　reduced　load　carrying　capacity　and　a　higher　frequency　repairs.　Therefore,　a　proper　and　objective　method　for　bridge　condition　assessment　is　important　to　help　the　bridge　owner　in　decision-making　of　maintenance　strategy　regarding　current　budget　year.　This　paper　gives　an　overview　of　procedures　for　bridge　condition　assessment　used　in　China,　United　States　and　some　European　countries.　Comparisons　of　national　codes　of　bridge　condition　evaluation　have　been　done　among　these　different　countries.　The　main　differences　lie　in　the　selections　of　main　structural　components,　the　methods　of　assessment,　the　category　of　condition　rating　and　the　maintenance　strategies　according　to　the　result　of　condition　rating.　Four　methods　of　calculating　the　condition　of　the　whole　bridge　are　used　in　different　countries　in　order　to　identify　the　urgency　or　scale　of　the　maintenance.　So　far,　there　is　no　national　code　for　special　bridge　condition　assessment,　such　as　suspension　bridge　and　cable-stayed　bridge.　Therefore,　the　general　guidelines　for　condition　evaluation　of　cable-stayed　concrete　bridge　are　given　for　the　revision　of　code　of　bridge　condition　assessment　in　China.
