The correct term is Pratt Truss, not Bratte Truss Both will have almost the same quantity of steel assuming that all other parameters like span, depth and loads are the same. The difference will not be of much consequence. read more
The correct term is Pratt Truss, not Bratte Truss. Both will have almost the same quantity of steel assuming that all other parameters like span, depth and loads are the same. The difference will not be of much consequence. The Pratt truss will have its diagonals in tension, and so there will be a little less steel in the diagonals. read more

The major difference is the placement of the diagonal beams as one goes towards the middle and the other truss goes away from the middle. read more
