Hi,
The is an existing bridge (steel girder and concrete deck), 87ft span and 14 ft wide.
There is no load-rating on the drawings for this bridge, however I am very sure that was designed for HS-20 truck.
1-When I contacted the consulting that designed the bridge, they said at that time (1978 to 1982) there was no requirement to state the bridge load rating on the drawings or specs !!! Does anybody it is true?
2- Will I be correct to tell the owner to put a sign of 72000 lbs. on the bridge ?
An Hs -20 : 8000+32000+32000 = 72000 lbs.
Is that a correct sign and load rating for the bridge?
Thank you for your comment and direction. I am not a bridge engineer and my practice is regular structural engineering. I apologize to all bridge engineers and don't mean that I am stepping on their toe. This request just came to me to assist the bridge owner.
Sincerely,
SKJ
