standard way to apply the force of a human being standing on a plate?

[Walterke]

As the title says:
Is there any standard way to apply the force of a human being standing on a plate?

European standard EN280 says I should apply a point load, but a point load in FEA results in much too high stresses where the force is applied. How is this normally taken care of?
