The main beams can be I-beams, trusses, or box girders, and can be half-through or braced to create a through bridge. To accommodate thrust, innovative designs like lenticular trusses and bow string arches are used, as no moments are transferred, allowing for horizontal forces within the superstructure.

What materials is the London Bridge made of?

The London Bridge, constructed in 1973, constituted a replacement for a 19th-century stone-arch structure with a concrete and steel structure. The bridge replaced a structure built of stone that had been in place for approximately 600 years. This structure was preceded by several bridges constructed of timber. The bridge served as the sole crossing of the Thames River until the construction of Putney Bridge in 1729. The bridge was inaugurated by Queen Elizabeth II in 1973.

What materials can you use to make a model bridge?

Building a model bridge requires choosing the right materials, such as Balsa or Basswood, popsicle sticks, toothpicks, paper, cardboard, and more. The choice depends on the goal of the bridge, which can be aesthetic or functional. Most competitions limit the materials available, so it’s important to choose the most efficient option for testing the bridge’s weight.

Designing the bridge involves determining the desired length, whether it’s for a world record or an easy project. Choose a truss design from the Warren, Pratt, and Howe trusses, and draw it to scale on graph paper. This will help determine the bridge’s strength and durability.

In summary, choosing the right materials and designing the bridge based on its purpose is crucial for successful construction. Choosing the right materials and truss design can greatly impact the outcome of the bridge’s construction.

What metals are good for bridges?

Steel is a versatile building material with a long history of use, particularly in bridge construction.
