I need to create a new beam type in open bridge. there are two different sizes. one is 12" tall X 3'-11.75" long and the other one is 12" tall x 4'-11.75". In Texas they are called slab beams, but I am not sure how to create two new ones.
Currently at OpenBridge Modeler CONNECT Edition there are the Bridge Type options as explained in this article at the links below. This includes the RC Slab Bridge Type, i.e., Reinforced Concrete Slab Bridge that are the simple deck-only structures, also known as slab bridges.

As shown in the screenshot below, user can access this first step of the bridge modelling inside the OpenBridge Modeler Workflow, highlighted at the top left, of your .DGN file; then, select the Home Ribbon Main Menu, also highlighted at the top left, to access the Bridge Setup Ribbon Group options where the Add Bridge button is.
Note that you can search our Communities site by keyword at the top to find older forum posts and wiki pages articles.

No, sorry; it's something else and will fall under the Beam Slab (P/S or RC Concrete Girders) type as they have Deck and Girders.
Spacing and cross-section of the Girders can be different, but they cannot be of different group types. For example: steel and concrete can't be mixed in OBM.
Despite your Girders may not be already available under the TXDOT typical girders you can still create them and add to the Libraries.
The Girders are selected at the Place Beam button from the Superstructure Ribbon Group when you first create the new input, or you can modify them later, at the Properties, as shown in the beginning of this other article:
You can't change the Bridge Type as there are bridge type specific details which get added internally, and it would cause issues.
this is the shapes I am trying to create. Maybe there are concrete beams in the program which are similar and I can modify. I don't know every type.
These are what slab beams looks like. There is a certain distance between them and the deck sits on top.
Monica, These beams already exist in the default OBM Beams Template library. You can simply use them. Remember to use "Beam Type" = Custom, in the Beam Definition dialog, to be able to select these beams from the OBM Beam Template Library.
