Theoretical Analysis of Carrying Vehicle LoadLimit for SubHealth Highway Beam Bridge[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2010,49(1):34-38.DOI:
Depending on the actual service condition of subhealth 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 subhealth beam is given.②The difference between the reliability of subhealth bridge and new bridge is analyzied
consequently
the problem about reasonable limit vehicle load is solved preliminarily in theory.
