| Abstract: | Depending on the actual service condition of sub health bridge, the following investigation is developed: ①The concept of damage limit state is proposed, from which the subject of the serviceability carrying capacity is revealed, then the evaluation path of serviceability carrying capacity of sub health beam is given.②The difference between the reliability of sub health bridge and new bridge is analyzied, consequently, the problem about reasonable limit vehicle load is solved preliminarily in theory. |

| Keywords: | sub-health beam bridge damage limit state serviceability carrying capacity carrying vehicle load limit reliability |
