Bridge Stress and Load Concepts

The video tutorial introduces the basics of bridge construction, focusing on different types of loads such as dead load, live load, and environmental load. It explains the concept of force and how it acts on bridges. The tutorial also covers the bridge deck, span types, materials, and forms used in bridge construction. Additionally, it discusses the elasticity of materials and the types of stress bridges experience, such as compression and tension.

What type of load is the weight of the bridge itself?

• Live load

• Dynamic load

• Dead load

Which type of load changes over time due to factors like vehicles and travelers?

• Live load

• Dead load

• Thermal load

• Static load
