WEBQUEST-BRIDGE DESIGN
FORCES:
1a. Compression-A force that squishes something together.
1b Tension-A force that stretches something.
1c. Buckling-An affliciton developed by people moving in and out.
1d. Shear-A force that causes material to slide past another in opposite direction.
1e. Torsion-An action that twists a material.
LOADS
2. Dead Load- Anything attached to the structure.
Live Load- Things that move in or on the structure.
Settlement Load- When soil beneath structure settles uneven.
Thermal Load- When the structure expands and shrinks with the temperature.
Earthquake Load- When the ground beneath a structure moves back and forth.
Wind Load- When wind blows on the structure.
Dynamic Load- When beams vibrate too much.
3. Live Load- too much weight breaks the structure but when renforced by a thinck beam it is less likely to bend and break.
Settlement Load- the structure sinks when settlement is uneven but when you put concrete pillars underneath it becomes stable.
Thermal Load- too much heat makes the structure break but if you put roller joints it gives the columns and beams freedom to expand and contrast.
Earthquake Load: moves the structure too much and the structure ends up breaking but when you renforce with shear balls it stiffens.
Wind Load- the structure couldn't withstand the strong winds and toppled over but if you add diagnal braces it stabilized th structure.
Dynamic Load- the structure vibrates too much so you add a thick beam and it becomes less likely to bend.
SHAPES
4. The triangle is the strongest shape because it is the most stable and rigid shape used in contrustions these days.
