A brief step by step guide on how to add internal diaphragms and end blocks for Australia Super Tee Beams.
Figure 1: Typical Australia Super Tee Beam Drawing shows both interior diaphragms and end solid blocks.
1. OBM already includes in the default Beams Template Library all of the standard Super-Tee sections from the AS 5100.5 Australian Bridge Design Standards.
2. Make a copy of the standard template and edit it to create a cross section resembling the filled in section for the appropriate beam cross section being used.
3. Now place the deck and beams in OBM in the typical manner in OBM. In the Place Beams command, you can create section variations to model the solid portions at end blocks and diaphragm locations.
4. The resulting beams can be seen in the images below
