| 摘要： | The report presents preliminary results and a detailed plan for an investigation whose objective is to examine the economics and technology of proof testing of highway bridges. Current practice of highway bridge structural evaluation in the United States and New York State is reviewed. It is noted that current codes do not include provisions for proof testing in bridge structural evaluation, and no standard proof-testing procedures are available. A reliability model is introduced to determine the proof loads required for acceptable structural safety. The framework of a proof-testing procedural manual is also outlined. An economic analysis is summarized including relevant costs and benefits. |
