Vehicle loading

(OP)
I am trying to establish the maximum point load for a 1m x 3m slab in a pavement outside a shop.  A lorry could park on the slab.  I have been told the point load should be 75kN but I cannot find any evidence to support the claim.

Has any one any code references that I may refer too, please?

RE: Vehicle loading

I'm in the US, so your codes are not familiar to me; however, in the US, that is not defined by code.  It is based on the expected vehicle wheel or axle loads and the repetition (load cycles) of such.

RE: Vehicle loading

The attached is an excerpt from the Alberta Building Code 2006 which corresponds to the National Building Code respecting this provision.  Note (1) refers to Appendix A which states that for vehicles over 9000 kg, special provisions may be required as provided in the Canadian Bridge Code.  I am not sure what that might entail.

RE: Vehicle loading

Have you considered AASHTO live loads such as H-2, HS-20, etc? you can do a search in eng-tips and get what you look for.

Many thanks.
 

RE: Vehicle loading

Are you in the UK?  If so, the relevant criteria is probably the HA accidental wheel load.  Is is a (characteristic) 100kN load applied over an area of 0.3m x 0.3m.

Have a look at BD37/01 in the DMRB.

Thanks for the reference.  I have a copy now.

I am trying to access a reinforced concrete pavement-light spanning 1400mm.  Would this be classed as a bridge?

Thanks again.

RE: Vehicle loading

I would suggest that you use the bridge design code to asess the loads, but other than that I would treat it as a regular concrete member(with holes of course).

Thanks all
