What Materials Are Used To Build A Suspension Bridge

This is a school science project Suspension Bridges. The early suspension-bridge towers were stone but now they are either steel or concrete.

To make the suspension bridge I used the following materials and tools.

What materials are used to build a suspension bridge. A suspension bridge is a bridge in which the deck the part that you drive across is hung below suspension cables on vertical suspender cables. We made it from square wooden dowel. The piers towers are built principally of local Pennant stone.

Typically suspension bridges are built with two tall towers and a cable that travels from one shore through the two towers and to the other shore. Brick was used as a subgroup construction material along with stone construction. The Tacoma Narrows a massive suspension bridge.

Caissons are large boxes or cylinders that have been made from wood metal or concrete. During the initial period timber and stones were used in the construction as they are directly obtained from nature and easily available. Building A Suspension Bridge.

In the early nineteenth century suspension bridges used iron chains for cables. Alloy steel of different classes is used in rivet steel plate and shape steel eye bar steel etc because they are more strong tough workable reliable and economical than ordinary and cast steel. It was selected to represent my school for district science fair.

Firstly the anchors that are going to support the cables need to be set into the ground. In the case of suspension bridges towers are built atop the caissons. Modern suspension bridges use a box section roadway supported by high tensile strength cables.

I would bet we are one day making more use of advanced materials now used in the aerospace industry to build. The history of suspension bridge goes back go the 15th Century where rope and woods were the prime materials of construction. Suspension bridges in their simplest form were originally made from rope and wood.

The Construction of a Suspension Bridge There are six main processes when it comes to the construction of a suspension bridge. Teaching Resources Useful Bridge Facts and Figures Materials The chains and suspension rods are made of wrought iron.

They are normally made from concrete and need to be set into solid ground as these support a big proportion of the deck. Stones Timber Concrete and Steel are the traditional materials that are used to carry out bridge construction.
