RE: U-Framed Pedestrian Bridge - OBM

Vlad,

Thanks for your input.

I have tried another method in which i created a false deck with two I beams on each side, put a vertical offset on the false deck so the beams will be on the correct position, then i created another deck without vertical offset, that way i can add the cross frames at the bottom of the slab because i have the steel girders and also add the stiffeners. Then turned off the display of the false deck.

Cheers.

There is no option to create by default a bridge of that kind.

You can try to model the bridge with the current functionality but you will not get a full model.

Things that I would do:

- the deck should be the Main element, the one that gives all the elevations

- the side girders I would model them like barriers

- the crossbeams I would model them with crossframes (you will need 2 "dummy" beams to create the crossframes); you can hide the dummy beams in the model

- the other parts like stiffeners for the main side girders I would model them like cells with Place Auxiliary by Path.

It will not be a 100% accurate design, but is better than doing it by hand.

Hope this helps!
