A girder bridge is a simple and inexpensive type of bridge made of a horizontal beam supported by posts or pillars. It works on the principles of compression and tension and is commonly made of reinforced concrete or steel beams. The biggest limitation is its length, but longer spans can be achieved by daisy chaining […]
Girder bridges are built on horizontal support beams made of materials such as steel or concrete. I-beams and box girders are commonly used for straight bridges, while box girders are preferred for longer or curved spans. There are four types of beam bridges, including rolled steel girder, plate girder, concrete I-beam, and box girder bridges. […]
Deck beams support the weight of decking and people on a deck and are typically made of 2×12 lumber. They need proper support through deck joists or slot and bolt technique, and must comply with building codes. A deck beam is a support post that supports the weight of decking materials and any person or […]
Box girder bridges are a common style of bridge with support beams bolted together to form a hollow box shape. They offer sturdier construction, are often made of prefabricated steel or concrete, and can be moved to another location. They are commonly used in highway overpasses and can support heavier loads. However, they can be […]
Plate girder bridges use two or more plate girders to support the bridge deck. They come in three types: deck-type, half-through, and multi-span. Cross bracing and vertical stiffening sections prevent buckling. Primarily used to support railroads, a plate girder bridge is recognizable through the use of two or more plate girders that support the bridge […]
