Study Notes
Bridge Structure
- Abutments in a bridge structure support the bridge's loads and distribute them to the ground, ensuring stability and preventing settlement.
Arch Bridge
- Arch bridges, particularly those with a continuous curved shape, spread compressive stress over the entire arch, providing added strength and durability.
Structural Forces
- Shear is a type of force in structures that causes deformation by applying a parallel but opposite force to two adjacent parts of the structure.
Reinforced Concrete
- Steel or plastic rods (reinforcement) in reinforced concrete serve to resist tensile forces, providing strength and stability to the structure by binding with the surrounding concrete.
