What are steel bridges made of?
steel bridges are made out of steel OBVIOUSLY !!!
Does concrete expand?
yes, that is why they put expansion joints on bridges. (: your welcomeyes, that is why they put expansion joints on bridges. (: your welcome

What are the different types of joints in steel structures?
The different types of joints in steel structures include welded joints, bolted joints, and riveted joints. Welded joints involve fusing steel members together using heat, while bolted joints use bolts to hold steel members together. Riveted joints use rivets to connect steel members through a hole punched in both pieces.
What are the effects of expansion and contraction in the design of bridges pavements and MRT lines?
- MRT and Railway tracksif a continuous track of metal is used, it will expand in hot weather and bent. trains running on bent tracks may be derailed. to prevent this, railway tracks are laid in sections with expansion gaps between them. A sliding joint between adjoining rails allows them to expand without bending.- bridgesboth concrete and steel bridges are built with allowance for expansion and contraction due to changes in the surrounding temperatures. Rollers and sliding joints allow for the movements of the bridges as it expands and contracts
How are bridges designed to stop expansion and contraction from breaking them?
Bridges are designed with a space at one end and rollers which can move to allow for expansion and contraction of the metal.
Why are there joints in bridges?
The space at the joints is there to allow for expansion and contraction of the length of the bridge depending on the temperature.
What is a cable used for in bridges?
Steel
What mineral mAKES steel bridges?
the same mineral that makes steel.
