    No, I mean 500 kilograms, 500 kilo-newtons, 500 kilo-pounds, ...

    What are the units for your load?

    Just want to point out that if you are designing this for a structure, especially one which people will be using, you MUST check your local and federal building codes. It may also be required that a certified structural engineer stamp the work.

    500 kg huh? Where did this figure come in? Did you account for seismic loading? Wind? Snow/rain? etc

    A 40 foot span is nothing to be approximating at.

    We don't give this sort of advice here. If you don't know what you are doing, you need to find a local source of info (a structural building expert) and have them help you.
