AASHO-IV Girder - Bridge Crane Runway
AASHO-IV Girder - Bridge Crane Runway
(OP)
I am trying to analyze a prestressed girder dated about 1960. The company wants to upgrade the bridge crane from 50 tons to 85 tons.
Does anyone have any information on the prestress used then? How about load tables? I have a copy of a 1971 PCI handbook. The concrete tests showed about 5000 psi.

Without the original design documents pertaining to that girder, you will have to verify its strength in some other way such as a load test.
