First of all, here is the Teddy .dat file link: three span box girder bridge.dat (4.8 KB)
Basiclly it’s a 3-span concrete single box with two cells girder bridge.
The cross section has 26 independent variables, like ‘H’ - box total height, ‘Wt’ - top slab width, ‘Tt’ - top slab thickness, etc
The cross section also has 38 derived variables.
The cross section can be drived by previous mention 26 independent variables,
I create an axis variable H (box height) in SofimshC
the result looks correct to me
BUT, the generated bridge has constant sections, NO variation along the axis
