What is Load?
In civil engineering, load is the force or weight acting on a structure. Buildings, bridges, towers, and other structures are designed to safely withstand various types of loads throughout their service life.
Definition
Load is any external force, weight, pressure, or impact acting on a structure that produces stress, deformation, or displacement.
Types of Loads
1. Dead Load
The self-weight of structural elements.
Examples:
- Beams
- Columns
- Slabs
- Walls
- Roofs
2. Live Load
Loads that change with time and use.
Examples:
- People
- Furniture
- Vehicles
- Equipment
3. Wind Load
Force exerted by wind on a structure.
4. Earthquake Load
Forces generated during seismic activity.
5. Snow Load
Weight of accumulated snow on roofs.
6. Impact Load
Sudden loads caused by moving objects or machinery.
Importance of Load Calculation
- Ensures structural safety
- Prevents structural failure
- Improves durability
- Helps in economical design
- Maintains stability
Load Transfer Path
Load → Slab → Beam → Column → Foundation → Soil
Conclusion
Loads are one of the most important considerations in structural engineering. Proper identification and calculation of loads help engineers design safe, durable, and efficient structures.
