Abstract:
The objective of this investigation was to demonstrate the feasibility of obtaining meaningful quantitative structural response data, suitable for rating purposes, from short span reinforced slab bridges by simplified load testing. Such simplified load testing could be carried out by regular inspection personnel, utilizing preweighed vehicles for loading the structures and collecting the resulting deflection data with readily available instrumentation, such as mechanical dial gages, etc. Quantitative in-situ load performance data, combined with conventional visual inspection, would provide a much sounder basis for load rating than visual inspection alone. Before such a rating procedure can be developed, however, it must be verified that useful data can be collected by the "low-tech" instrumentation alluded to.
