| Double Core Unit | A precast concrete beam with two hollow cores running through it, used to reduce weight while maintaining strength.
|  |
| I Beam | An I-beam is a structural steel member with an I-shaped cross-section that's used in many construction projects. These beams have the capacity to withstand various types of loads.
|  |
| U Beam | A type of steel beam, which is a structural steel product with multiple uses mainly in the construction sector. U-Beams are also known as a parallel flange channel or C Beams. They typically can be welded together to form I-Beams.
|  |
| T Beam | T beam bridges have cast-in-place, reinforced concrete beams with integral deck sections to either side of the tops of the beams.
|  |
| Inverted T Beam | An inverted T-section concrete beam is a type of beam that has a cross-sectional shape that resembles an inverted letter "T". The top of the beam is flat, while the bottom of the beam has a flange that extends out on either side. Inverted T-beam is used when the beam is subjected to hogging moments.
|  |
| Log Beam | A large piece of wood, or log, that is used to create a structure.
|  |
| Plate Girder | A structural element made of welded or bolted steel plates that is used to support heavy loads and spans in bridges.
|  |
| Precast Concrete Panel | A bridge deck made of a series of prefabricated concrete panels that are cast off-site and then installed at the bridge site.
|  |
| RSJ and U Beam | Rolled Steel Joists and Universal Beams are are both types of steel beams used for structural support in construction and engineering. |  |
| Stringers and Transom | Steel beams which span under the roadway and carry the loads of the roadway to the trusses or beams.
|  |
| Bailey | A type of pre-fabricated, modular steel truss bridge used for temporary or emergency crossings; quick to assemble without heavy equipment.
|  |
| Box Girder | A hollow, rectangular beam—often made of steel or concrete—that provides high strength and stiffness, used for longer spans.
|  |
| Truss | A beam made from a connected framework of triangles, efficiently distributing weight across long spans.
|  |
Frame
| A beam system where horizontal and vertical members form a rigid structure, typically seen in rigid frame bridges.
|  |
Girder
| A large, solid horizontal support beam (usually steel or concrete) that holds up the bridge deck and transfers loads to the piers or abutments.
|  |
| Unknown | The beam type is not recorded or cannot be identified based on available information.
|
|
| Not Applicable | No beams are used in the structure, or the structure type does not involve beams.
