Bridge Wizzard - Plate for deck and frame for beam

Question:

Comp_NU63 shown in blue text should be the one used for the composite section as defined using the bridge wizard. However, in the model the black text Comp_NU63 is used but does not appear to be a composite section


So I am not sure why this is the case and if the composite section is modeled correctly. In the bridge wizard, I used plate for the deck and frame element for the beam.

Other issue is the girder should have a separation from the bottom of the deck or be flash. Appears to be embedded in the deck. It is center-top and offset is 8” as input in the section.

Last item is – Is it possible to include superelevation of the deck in the bridge wizard ?

Thanks so much.


Answer:Hi,

1. Since you selected ‘Deck as Plate, Girder as Frame’ as Modeling Type, the non-composite section is made.
Composite section includes slab part. It should be excluded if you want to make slab as plate elements.
2. For ‘Deck as Plate, Girder as Frame’ as Modeling Type in the wizard. midas Civil consider Haunch Height as a half of thickness of deck plus haunch height.
Please refer to the figure below. Apologies for your confusion, we will modify this for the future development.
For now, you should input a half of thickness of deck plus haunch height as “Haunch Height”.



3. It is not possible for the present. We will consider that in the future development.

Thanks & Regards,
