All materials expand when heated and contract when cooled.
Bridges are especially vulnerable because the entire bridge is surrounded by air, and it doesn't have the ground below to act as a heat sink.
Without the expansion slots, the bridge would run the risk of buckling when heating, and pulling apart when cooling. This could damage a bridge.
Uncontrolled or unsupported cracks, for example in the middle of a span could be very dangerous.
What else can I help you with?
What do you call the type of engineer that designs bridges?
civil engineers, structural engineers, and architects are the main bridge builders.
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
What does civil engineers create?
Roads and bridges.
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 does an engineer design?
They usually try to make the car they are designing, more fuel efficient, safer, and try to come up with ways to improve the current design.
Why do engineers design bridges with expansion slotsions?
Because bridges expand and contract with the change in temperature. The expansion joints allow the bridge to 'flex' as the temoerature rises and falls, ensuring the structure doesn't buckle or collapse.
What type of engineers design bridges?
Civil engineers and Structural engineers.
Why there are spaces between bridges?
To allow for expansion and contraction.
