Bearing Width for Manhole Covers

[Erasa]

Hi Engineers,
Is there any standard code that specify minimum bearing width (correct me if I am wrong) for manhole covers as attached

Heheh, oh how interesting you asked this question now. To my knowledge, no.

However, please look at this topic: [URL unfurl="true"]http://www.eng-tips.com/viewthread.cfm?qid=414908[/url]

We've gotten into quite a debate on what the manhole frame supported shear width is for a wheel load.
