Study on Operating Vehicle Load Limit of Sub-Health Bridge
Depending on the actual service condition of sub-health bridge, the following investigation is carried out: 1)The 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.2) The difference between the reliability of sub-health bridge and new bridge is analyzed, consequently, the problem about reasonable limit vehicle load is solved preliminarily in theory.
