## Live Loads

## Live Load vs Dead Load

## Dead Loads

The major difference between live loads and dead loads is:

- Dead loads can be calculated accurately as they are constant but the live loads can not be calculated exactly.
- So, live loads require a greater value of safety factor than dead loads. Live loads are given a safety factor of 1.6 and dead loads are given 1.2 in structural design. Basic equation of total live load and dead load calculation is:

U = 1.2 D + 1.6 L
