Bridge Inspection Decision Making Using Sequential Hypothesis Testing Methods

摘要

Bridge Management Systems (BMS) are decision support systems used by highway agencies in selecting appropriate maintenance and rehabilitation (M&R) activities and in allocating available resources effectively among facilities. BMS decision making is based on the condition of bridge components. Their predicted deterioration, and the cost and effectiveness of M&R activities. Traditionally, bridge condition assessments have relied mainly on human inspectors; their results have generally been qualitative and subjective. More detailed inspections requiring some degree of destruction to the bridge, like drilling the deck to inspect for chloride contamination, have also been used.
