Loads on Bridges
In bridge engineering, a load is any ___________or weight that acts on a structure and must be supported by it.
Force
When determining load capacity for a bridge, what are the 2 temporary loads and which one is the only permanent load?
Temporary- Live and Environmental
Permanent- Dead
Steel is used in many bridges instead of wood because it is stronger and _____________________?
If a drainage system is not properly assembled on a bridge, what load needs to be considered in this situation?
Environmental Load due to Rain Water build up
BONUS ROUND
Why is concrete often mixed with steel bars inside it and what is it called?
Steel makes concrete stronger with REBAR and handle pulling forces. Helps it not to crack.
What are the 2 most popular methods for combining loads when designing a bridge? (must have full names)
UBC-Uniform Building code
ASCE-American Society of Civil Engineers
Truss Bridges are popular because they_____________________________?
They use a relatively small amount of material to carry relatively large load capacities.
What force acts on the top of a bridge and what force acts on the bottom of a bridge?
Top-Compression (push)
Bottom-Tension (pull)
There might be more cars in New York than in Colorado, so the live load amount would be more in New York.
